Why do my Burned CDs not Play in my CD Player?
January 27, 2012 | 
Author So you just burned a mix CD of your favorite tunes for a road trip you and your friends are going on. You play the disc back on your computer, everything works like a charm. You might have even tried playing it back on your new home stereo, and just like on your computer, it plays fine. You head out, pop the CD into your car stereo you bought in 1998, and………nothing. The disc just spins and you get no playback. I’ve had this happen to me on numerous occasions. And have always wondered, why does my CD play on some players yet not on others? There are a few different things that factor into this.
1. CD-R vs. CD-RW.
You should be burning your audio CDs to CD-R media, not CD-RW media (CD re-writable). Some newer players will play CD-RW discs. But for the most part, the majority of audio CD players will only play CD-R discs.
2. Burn speed.
Each brand of CD-R has a certified maximum burn speed, which is expressed as a multiple of the audio playback speed. So, a disc certified at 24x can be burnt at 24 times faster than the audio CD will be spinning when it is played. You must set the burn rate in your CD duplication software according to the disc’s specification, or the data will not be written reliably. This can result in skips, or CD-Rs that will play to a certain point and then just stop. Ideally you want to burn your CD lower than the certified speed, to take into account manufacturing defects in your burner or the disc.
3. Brand of CD-R
If you have been burning CDs for a while, you probably have noticed that some brands of CD-Rs work well in some players, and some do not. CD-R discs are said to be “burned”. When you burn a CD-R disc, a focused laser beam darkens the chemical dye on your disc to mimic the bumps and flat spots that are generated on a replicated disc. (For more info on the differences between burning (CD duplication) and pressing (CD replication), please read my last article.
http://ezinearticles.com/?The-Differences-Between-Short-Run-And-Long-Run-Cd-And-Dvd-Duplication-And-Replication&id=158412 )
Unfortunately, sometimes the mimicry is not perfect. And if you have an older CD player that was not designed to play CD-Rs, it will not always play them reliably.
By all means this is not a complete guide for troubleshooting your CD burning problems. But it should at least give you a little more insight into why those darn mix CDs you burned will not play in your home or car stereo! My best advice is that you burn your CDs according to the certified maximum burn speed (lower if possible), and try out different brands of CD media until you find one that works best in your player.
What Happens To A File Once You Hit Delete
If you chose not to tinker around with your Windows operating system, then the file automatically goes in the Recycle Bin. If you ever decide you still need the file, you can simply search through the trash (a funny concept Microsoft makes us go through) and you’ll find your deleted file intact and easily recoverable. However, if you disable the Recycle Bin, things will go slightly different.
Most of us consider deleting a file permanent. After all, you can’t see it in the directory structure so it’s definitely not there. Unfortunately (or well, fortunately, depending on how you look at the situation) when it comes to computers, seeing is not necessarily a premise for believing. A file doesn’t get permanently destroyed and eradicated from your memory by simply deleting it from the directory structure. Instead, it is kept safe in a free memory area, stored in case you change your mind and need your file back. What gets deleted is the link pointing towards the file, so if you would compare a file to a book page, deleting the file does not tear the page out of the book, but rather deletes the page’s index from the table of contents, represented by the file system here.
Still, your hard disk space is not infinite, so eventually the space your deleted files gets crammed into will fill up and no more “closet” space will be available. What the operating system does in such a case is overwrite the old deleted files with newer deleted files, so there’s a certain time limit in which you could recover your lost data. For example, if you deleted a file from your hard drive a year ago, the chances are slim that you’ll find it intact in the “closet” area. Instead, if you deleted it yesterday there’s no chance it got overwritten.
Of course, data recovery techniques have been constantly improving and specialists can now recover the data even after it has been overwritten! Some companies boast the fact that they can recreate files that have been deleted and subsequently overwritten in the lost memory sector by up to 10 times. However, after 10 overwrites, there’s a good chance that the data that is recovered is not entirely intact and some parts might be missing.
Just like there are programs that help you recover deleted data, there are other ones that help you permanently delete it! Sometimes you’ll want to permanently destroy some data you stored on your PC and your closest resemblance to a paper shredder is such a data deletion tool. As data recovery technology is on a constant rise, there’s a chance bits and pieces of your “permanently deleted” data can still be found, so it’s best not to count entirely on that if you really, really don’t want someone to find out what you stored on your hard disk.
What Are The Laws Regarding DVD Use And Duplication
Because of all the laws and regulations regarding DVD duplication many people are confused as to exactly what it entails. People are even uncertain if they have, the ability to create duplicates of the DVDs you already own. The unfortunate reality is there are no solid pieces of advice when it comes to DVD duplication for personal use. The thing is, each DVD you have in your collection, even though you purchased it, is actually copyrighted, and owned by another person. You are essentially purchasing the right to use it. Within the copyright laws, which are not at all clear, it is stated that after purchase, the DVD movie can be used as defined in “Fair Use”.
This means you can bring a few friends or family members over to your home to watch the movie, show it during a Cub Scout activity, or other such activities. The only provision in this aspect is that it cannot be used commercially. This means you cannot legally charge anyone to watch the movie, under any circumstances. So legally you can’t ask your buddies to pay for watching one of these DVDs.
When talking about DVD duplication for personal use, the law is not at all clear. The reality is the chances of you getting into enormous trouble for taking a DVD you already own and duplicating it for your own personal use such as if, the original copy breaks or becomes unwatchable, is extremely unlikely. However, personal use is the keyword in this whole statement. If you duplicate a DVD and then lend to a friend or family member, this is a clear infraction of the fair use policy. By ignoring this policy and the copyright laws, you are putting yourself at risk of facing prosecution for the DVD Duplication.
The best advice anyone can give you is to ensure that any DVD duplicates you create are in a safe and inaccessible place for any visitors you have. If they were to get one or you were to lend one to a friend, you could be facing serious charges that include high fines and possible imprisonment. The copyright laws are in place to ensure that the owner of the copyright is protected from any types of fraud and illegal activities, which includes DVD duplication of any form. It is best to simply avoid making any duplicates of any DVD movies to protect yourself and your friends. Purchasing the movie will help in support of your favorite actors and directors.
What is SAP and What Does SAP Stand For?
SAP is one of the top Enterprise Resource Planning (ERP) software in the world. SAP is the brainchild of five IBM engineers who broke off from IBM and founded SAP AG in 1992. It drives efficiency and value to the bottom line of large, mid-size and now smaller organizations by redefining how business should be done. SAP solutions deliver real-time visibility across the entire enterprise and are not limited to top management, control engineers or the IT team. It can be used by every individual in the organization. That said, however SAP training courses are a large and important component of the change.
SAP the acronym stands for Systems, Applications and Products in Data Processing but SAP the ERP system stands for increased efficiency, streamlining the supply-chain network and overhauling the entire business process of the organization. Companies that adopt SAP can look forward to a total makeover before they are done. The transparency that follows, enables faster information processing and making decisions with ease and no fear of risk. SAP, having evolved for over 3 decades is agile enough to adapt to most industries. SAP is not offered in modules any more but available as various solutions tailored to each industry.
Enterprises must acknowledge that humans are as much a part of the chain and focus their efforts on making their personnel proud stakeholders in their new venture. To leverage SAP functionality SAP training courses are invaluable. SAP courses can help executives, finance managers, accountants, engineers and IT mavens. SAP functionality is truly enterprise wide. If one wants to replace an outdated and inefficient IT architecture, if one wants to implement business process change, if one wants to maintain a competitive advantage in the field, SAP is the answer.
SAP is available today in country specific and industry specific versions in 28 languages at last count. However to get the most out of their SAP investment enterprises must equip their employees with the requisite skill sets. SAP courses can equip them to meet all the challenges of the marketplace: to bring products to market faster, get more out of procurement and eliminate duplication of effort. SAP training courses will ensure that key executives are well prepared to lead change. It will enable employees to have the right skills supported by tools and processes that set them up to succeed. All employees will feel confident of their skills and proud of their contribution to the company. It will help build ownership and boost morale. SAP courses will make sure that employees are prepared to succeed on the first day of the launch.
Taking SAP training courses is an ipso facto guarantee of a well-paid job in the worst economic crunch. SAP courses can jumpstart any career whether as a consultant or an employee. These skills are in great demand. Especially a proven knowledge of SAP applications via SAP training courses and certification can fuel ones career and become a passport to a whole slew of opportunities. In today’s competitive market if one can demonstrate mastery in essential business and technological skills, the sky is the limit. The SAP trained can enjoy a definite advantage over their peers.
Mini DV Players
Mini DV players are available with many different features. Sometimes the technical terminology becomes a little confusing for the layperson. You may have doubts regarding the compatibility of Mini DV cassettes with certain players, or what kind of editing features are available with a particular player. It is best to research extensively before purchasing a Mini DV player, and if you have doubts, you can always get them clarified at the DV player retail store. Also, many websites offer advise on what is the best Mini DV player to suit to your needs.
The Mini DV players mostly double as recorders. They are available for both amateur and professional use. For professionals like wedding videographers and filmmakers, JVC has come up with many innovative players. The JVC HR DVS 3U, for example, is a player as well as recording system. It is very convenient to use, since the Mini DV cassette can be directly inserted into and played by the DV player. There is no need for connecting the camcorder to a VCR using a jumble of confusing wires. It has good editing features, and is capable of converting analog signals to digital. JVC’s HR DV S 3, on the other hand, is a double deck Mini DV VCR which also converts Mini DV to S-VHS format after editing, apart from being a player and recorder compatible with almost all Mini DV cassettes.
For amateur use, the Panasonic Professional DV Proline offers many features like a high sound to noise ratio, four video heads, timer programming, and a clear image quality. This device is meant simply for playing and not for recording purposes. Many users have mentioned problems like the absence of remote control or parental locking mechanism, as well as the lack of built in monitors, which means the player needs to be connected to a VCR, but this player is good for amateur or home use.
With many brands of Mini DV players flooding the market, there is always one out there suited to your needs. With a little patient research, you will be able to locate the best Mini DV player in terms of features, size, recording/playback quality, and price.
How to Make A Great Press Kit – A Musician’s Guide
As an owner of an independent record label, I often get asked how to put together a great press kit. I have found that young musicians understand their music, but are often intimidated by the marketing end of the business. In this article I will help you figure out how to position yourself, whether you are a Latin female vocalist building her base, or an upstart garage band just looking for a break.
What is a Press Kit:
First of all, there is nothing magical about the term “press kit”. All we are talking about is a little background on you/your band, some basic facts, good quotes about your music, a couple of good pictures, and a sample of your music. You will use this to send to newspapers, lawyers, radio stations, A&R reps, promoters, and anyone else who is willing to spend five minutes reviewing your material. Additionally, on the internet you will hear about an electronic press kit, or EPS. An EPS is the exact same thing as a conventional press kit, except it is downloadable as an electronic file instead of a hardcopy form which must be mailed.
The main purpose of the press kit is to generate interest in the artist and their music.
What to include:
Include a limited amount of background information on yourself. It is fine to say where you are from, but no one really wants to hear about every singing performance you did during elementary school. Sometimes less is more.
Talk about your music. Who do you sound like, and who does your music remind people of. The reader needs to be able to have a good idea of what your music sounds like just from your description. Be thoughtful and feel free to be a little funny here (but stay professional). Saying something like your band sounds like a cross between “Maroon 5 and Green Day after 20 cups of coffee” helps the reader understand. Remember, if you don’t generate enough interest in the first minute, they will never listen to your demo.
Talk about what you are good at. What makes your band special and different from others? What skills and experiences do you bring to the table? Remember if you are looking for a record deal, you need to prove to your reader that you have all the right ingredients for them to spend hundreds of thousands of dollars marketing you. Launching a new artist is risky, so you need to help the record exec understand why you are a solid investment.
Include quotes and/or press clippings as you generate them. A good quote from a reputable source (not your brother-in-law) can add a lot of credibility to your press kit. It lets the reader know that you have already been reviewed and your material is worth listening to. Ninety percent of press kits unfortunately end up in the trash, some good quotes and positive reviews can create the momentum necessary to get heard, and who knows – maybe even become famous.
You can go with one page dedicated to a bio (biography), and a separate page focused on quotes about your music, or you can combine the two into what some people call a “one pager”. My personal preference is to boil everything down to a tight one pager. My desk gets cluttered and papers get separated. If you have you quotes separate from your bio, there is a possibility that I could misplace one or the other. With the advent of digital photography and high quality color printers, it is even possible to include a small picture on your one pager to make it even more complete.
Make sure the overall language and tone of the press kit is consistent with your image. If you have someone help you write your bio, make sure they have heard you music and know what you are all about before they hand you something that might sound great, but isn’t about the real you.
Include a couple of different 8×10 pictures that show off different features about you and your band. Include shots that would be appropriate in a news article, but also highlight your key assets from a visual perspective. Your press kit should look professional, but your pictures should reflect your style and music, so you pictures can be much more crazy and creative. Make sure you clearly label the picture with you name and contact information.
If you don’t have good pictures of your band, one of the best ways to get some is to go to a modeling agency and ask for a referral to a good local photographer. These photographers are often willing to do some great work for around $300 for the whole package. Make sure you get an agreement upfront that you own the copyrights after the shot and get the high resolution digital images on CD (with a copyright release you can print these photos at any major retailer). A photographer who does work with models is very different from a photographer who takes family pictures. They have a much better idea of what you want, they will encourage your creativity, and they are much more willing to give you the copyrights.
A current gig sheet can also be useful showing where you have recently played and where you are playing in the near future. This can demonstrate that the music is current and has a following in the community.
And of course, your music. Send a high quality CD demo, preferably mastered if you budget permits. Avoid burning your own CD on your home computer with a stick on label – it looks cheap. There are many new CD duplication services on the internet that will manufacture you CD with a printed color insert, and on disc printing even if you only want a few copies (CD replication is for batches over 1,000 but CD duplication is for batch sizes as small as 1). Expect to pay around $5 a retail ready disc for 1-5 CDs, with prices dropping off for larger batches. Make sure you clearly label the CD and the case with you name and contact information. The worst thing in the world that could happen is that they love your music, but they have already lost the rest of the press kit and don’t remember the name of the band.
What Not to Include:
Don’t oversell yourself. Saying that you are the greatest band that ever lived, might be true, but it probably isn’t. Be positive and promote yourself, but focus on statements that are credible. People in the music business hear hype all of the time, and for the most part are numb to it. Hype is good to use with the general public on things like posters (they often believe it), but your press kit reader is more sophisticated and will see it as cheap theatrics.
Including too much of your personal history can make you seem like an amateur with nothing meatier to talk about. Your reader wants to understand your music today, only your psychologist needs to know about every little detail of your childhood.
Don’t include anything that makes you look too desperate. You want to come across as a quality professional artist. Remember, you make great music. If your band is called the Chicken Heads, then it might be cute to include a rubber chicken in the box, but otherwise I would stick to the basics – bio, quotes, gig sheet, pictures, and music.
How to Package It:
Include a professional looking, personalized cover letter targeted at the person you are sending the press kit to. Your message needs to be different if you are sending it to an A&R rep at a label seeking a record deal, versus sending it to your local newspaper for a review in their music section. Be brief and to the point. Also, be clear and state exactly what you would like from them.
Put it all together in an organized package. Since you are most likely mailing your press kits, make sure that the CD does not bend the photos, and that your kit will arrive looking the way you intend. You may even want to test a press kit (send it across the country to a wrong address, and then it will come back to your return address) to evaluate your packaging.
Your Music Is Art, But Your Press Kit Is Business:
Remember, be professional. The person you are sending this press kit to probably gets hundreds of them, most of them are garbage (and that’s where they end up too). Your music can be crazy and wild, but your press kit needs to be more business like. You are asking someone to spend their valuable time reviewing your material. You may also be asking them to enter into a high risk expensive financial relationship with you. The person you are dealing with is in the music business, they need to make a living. The only way they can do that is to deal with real talent. By presenting a professional package you give them confidence that you are dedicated to making great music, and not just messing around.
A Word About Unsolicited Press Kits:
Avoid wasting your time and money sending a press kit to someone you have not talked with already. Always call and make contact first, ask who you should send it to and what their process is. If possible, have someone who knows the person act as an intermediate and make the initial introduction (this can work wonders). The music business is all about contacts, create and leverage your network. After sending your press kit, call in a couple of weeks and follow up to make sure they received it and got a chance to review it.

DVD Duplication v/s DVD Replication
Duplicating means to copying, Identical, Exact copy of one thing or reproduction. It is act or process of reproducing something. It is carbon copy, image, and copy. Bearing exact features of the original, from which the copy is made. It therefore means a copy that corresponds to an original exactly
To replicate means an act of duplicating or reproducing something, an echo or reverberation, a copy or reproduction. Again we see that is a process of duplicating or reproducing something. It is a Duplicate made by original maker.
Here we come close. Both words have similar meaning just bearing a thin line to differentiate each other.
Conclusion drawn from the above text is the copies can be made or Duplicated or anything can be identically be copied manually or by help of machines (photocopies, imaging machines etc) by any individual.
Technology has played wonders. Duplication of a document in thousands of numbers can be obtained in seconds. High tech copiers with digital technology have gained market and importance due to speed, quality and due to the special feature of being cost effective.
Media is an initial and essential ingredient of our high tech digital world. Advent of computers, it advancements, passing through different stages and coming up to the present stage where we have smaller faster units, requiring to occupy small physical space, storage devises that too occupies larger spaces and copying and storage used to burdensome.
DVD Duplication is the process of duplicating data onto an existing pre-made disc. This disc is known as DVDR, short for Digital Versatile Disc Recordable, respectively.
DVD Duplication is same as to duplicating other storage media. In all cases your are duplicating data onto existing media. Existing media is the key. The process begins with a pre-made disc that is capable of receiving recorded data.
Duplicating DVD is simpler, faster and more cost effective.
DVD Replication is the manufacturing process that essentially replicates or “clones” your original master. A Glass Master is created from your original master.
A Glass Master is created from your original master.
It is from the Glass Master a set of “stampers” are made. The stampers or molds are the blueprint for DVD replication process. After mounting stampers into a High Tech injection mold machine. During molding process, a replica of the mold is created in the form of a plastic disc. The disc is then coated with a micro-thin reflective layer of aluminum.
Finally DVD replication process involves application of a protective lacquer that is spun onto the disc and then hardened by ultraviolet (UV) light. The replication process is now complete. DVD Replication therefore is longer, more costly process but ensures quality, accuracy and speed from start to finish.
CD-DVD Duplication Makes You Store Music in a More Lasting Digital Format
Music plays a major role in people’s lives. Music makes life more meaningful. It shares the joys and pains we experience in our everyday lives. In other words, it makes us whole as we take on the rough roads of life.
Music format has gone a long way since time immemorial. For people who have gone through several generations, many of them especially the music lovers are surely familiar with how music was stored way back then and how several formats have evolved through the years. From the music records of days old to the cassettes to the CDs and DVDs, it’s amazing to think how technology has helped advanced the process of storing music into multi-media digital format.
As to how music is stored on a CD, it’s actually audio tracks that are stored. These are audio files in .cda file format that can be found on music CDs sold at music stores. Different formats are used in storing data on a CD but the most widely used especially in CD and DVD copying or printing are the CD-DA (audio) and CD-ROM (computer data).
The process of encoding data on a CD is quite complex but we’ll explain the method in a simpler manner for your understanding. First of all, a single spiral track containing data exists on a CD. This track begins in the center of the disc moving outside and is made up of bumps.
Data (songs) is tracked through the bumps on a CD. Subcode data is utilized to encode the laser position in the track and the song titles. To minimize misreading of bumps or errors, error-correcting codes are used. To allow a CD drive to recover easily from burst errors caused by scratches on a CD, interleaving of data is done on the disc.
Compared to the CD, the DVD (digital versatile or video disc) has a larger storage capacity in terms of running time, the number of songs that can be stored and the quality of audio. The process of storing data is quite similar, though. The best part, however, is the fact that not only music can be stored on a DVD but even music videos. This provides a more exciting experience to all music fans.
In fact, the latest trend in the music industry makes use of both CDs and DVDs. Many recording companies have actually introduced a unique packaging that contains a CD album with a bonus DVD that includes several music videos of the featured artist. This newest type of CD packaging eventually led to the emergence of the dualdisc format. Dualdisc refers to a single disc in various formats and that can be played on all types of CD and DVD players. It also boasts of great DVD features such as surround sound and visuals and data that can be read by computers.
As music continues to be a part of life, there will always be great opportunities for CD and DVD production whether for commercial or personal purposes. Let us rejoice then that music will be in our midst even until forever.

CD and DVD Duplication – Lasers
Laser technology is a vital component of CD Duplication, in fact it is the foundation upon which the technology of CDs developed and therefore integral to the processes involved. As CD technology has developed over the past 40 years, so too have the lasers used developed and advanced to produce new capabilities and uses of CDs.
With lasers being a vital part of the Duplication process, not just in reading CDs, the development in laser technology has therefore had important implications for CD Duplication, while the laser process used during duplication will impact the lasers used at the CD reading stage.
Originally, CAT lasers were used to read CDs, with an infrared wavelength of 780 nm. Subsequently the wavelength has been reduced to produce DVDs, using a reading wavelength of 650 nm, while Blu-Ray discs use a lower wavelength still of a violet wavelength of 405 nm. This development of using smaller wavelength lasers has been to increase the amount of data that can be stored onto a disc. Particularly with the development of using discs to store imagery and video, rather than just audio and ROM data, much more data has been needed to be stored on a single disk. With the physical size of discs remaining the same, this data has had to be packed much closer together in order to fit it all on. As a result, lasers with shorter wavelengths have had to be developed in order to read this now more compact data storage.
Inevitably, as well as requiring a shorter laser wavelength to read a disc, so shorter laser wavelengths have been required in order to ‘write’ the data onto the disc during the CD and DVD Duplication process. During Duplication, a laser is used to change the reflectivity of the disc surface, with these variations in reflections detected by the laser in the disc reading device. It therefore follows that the changes in reflection of this disc must be shorter, and therefore the laser that creates them must also be so.
Lasers used during Duplication are called Laser Beam Recorders (LBR). These laser machines can vary the wavelength of the laser, depending on what is needed and what the disc is to be used for, to create CDs, DVDS, Blu-ray and other disc types. LBRs use either Photoresist Mastering or Non-Photoresist Mastering (also known as Dye-Polymer mastering) to write to the discs. Photoresist mastering uses discs with light-sensitive surface materials that change reflection when exposed to the laser, while Dye-Polymer mastering use discs with a Dye-Polymer surface material which evaporates when exposed to concentrated energy produced by the laser at the required points on the disc. Each of these techniques has different benefits, and also requires a different laser setup to write to the different disc types.
Lasers used to Duplicate a disc are much more powerful than those used to read the disc. This makes sense, as a reading device does not want to alter the disc surface and affect the data stored on it, whereas this is the exact purpose of a LBR. An LBR needs to operate at a power setting that produces enough energy to alter the surface of the disc, which is currently around 200mW, while disc readers run at around 5mW. This allows readers to run at a lower power, saving energy, and also allows a significant differentiation between the two power settings to avoid readers inadvertently causing damage. In order to allow this, disc surface materials that can be moulded at the higher power setting while remain unaffected at the lower setting of the reading lasers have to be selected.
What Makes A Good Team Leader?
How many times have I been asked this question? (The title of this article). The answer is plenty of times. I attend an interview for a position of authority and am asked, amongst other things, what constitutes a good team leader? In this article I will be writing about the way in which I would reply to this question etc.
In my career thus far, I have been a team leader for two different companies and have also been a member of many different teams, who have been run by a numerous different team leaders. This has given me, in my own opinion, quite a good understanding of what is required to be a good team leader.
Good, positive and quick decision making
There is nothing worse than being in a team whose leader is quite weak, in-decisive and lacking in confidence. It sends a wave of uncertainty through the time and leaves the members of that team feeling frustrated.
Communication
A team leader who is unapproachable is, in my opinion, a poor team leader. Any member of the team should feel comfortable and happy to be able to talk to his/her team leader about a variety of matters. This would include business matters of course but could also include any personal difficulties that they may be going through.
The team leader should also possess the ability to convey messages from the company to his staff, as well as communicating what he expects from them, work wise, for that particular day and week.
Motivation
A good team leader will have the ability to keep his or her troops motivated throughout the day and week. They can do this by operating various challenges such as the best employee of the month receives a box of chocolates, the worst employee is not allowed to speak or be spoken to for one hour, as way of punishment. Just a bit of fun and games, which can be judged by the amount, and standard of work that each member completes. This is just one of many ways to keep the troops thinking and working.
