CD-Rs have a metal reflective layer that is essential for the disc to function. The best reflective layer material is gold because it is chemically inert - meaning it will not react and degrade as other metals might. The second best layer is silver, which is more reactive chemically, but generally cheaper and currently more widely available. Mitsui, HHB, Apogee and Quantegy, among others, make discs containing gold.

Retiring a disc: I don't need that directory of MP3s backed up any more, etc. Or maybe I was using that cd-r to temporarily shuttle a bunch of OTR shows from place to place. Dent and Ding sale: maybe I closed the disc before I wanted to and re-burned that session again on a fresh disk. Maybe I put the same file on twice or something else goofy like that. These are like "cosmetic damage" - the CD will work just fine, the contents are just not what I wanted them to be for my own usage.

It all depends on what you are using the media for. For general data, photographs & back-ups Verbatim, TDK, Prodisc & Intenso are all suitable. Verbatim & TDK are supplied with a Jewel Case whereas Prodisc & Intenso are supplied bulk wrapped & unbranded which means the discs are shrink wrapped & without a case. Unbranded means there are no markings on the disc eg. manufacturers name etc.

Yes and no! If the disc has been left OPEN it can be written to again, although no existing data on the disc can be overwritten. This is known as multi-session recording. Data is written to the disc in sessions and if the session is left OPEN then another session may be added later (up to 99 sessions can be written to a single disc!). Generally, when writing to CD-Rs they are CLOSED by default, meaning that no further writing can be done.

It is very difficult to estimate the life of a CD-R or CD-RW because there are many factors such as temperature and humidity, exposure to light, dirt and contamination, and handling and scratches, which can affect the life of a disc.

All of our CD recorders work with either blank CD-Rs or CD-RWs, so you won't be locked into exclusive use of one or the other by your hardware. Choosing between the two formats really comes down to your intended uses for the discs you're burning. Although the "R" in CD-R stands for "recordable," this is a "write-once" technology. That means anything you record on a CD-R is permanent.

We sell our products in complete sets - however, there are more than thirty products available from Sound Ideas that are comprised of one or two CDs only.

Yes, the content on the DVDs is organized in such a way that it is easy to create your own CD-Rs from DVD. However, there are some things that must be paid attention to: Keep the path identical. For example, if the path to Windows XP Professional on a DVD is \English\WinXP\Pro\, be sure to put all of the files on the CD-R in the same path. CD-Rs can only be created and used in accordance with the MSDN Master End-User License Agreement (EULA).

The only discs that a DVD player is guaranteed to read are DVD discs. Support for CD-ROM, CD-R, and CD-RW may be included, but is by no means guaranteed. CD-R was designed to be read by an infrared 780nm laser. DVD uses a visible red 635nm or 650nm laser, which aren't reflected sufficiently by the organic dye polymers used in CD-R media. As a result, many DVD players can't read CD-R media. Some DVD players come with two lasers so that they can read CD-R.

On an injection molded or "pressed" CD, the grooves (called "pits and lands") that represent the binary data on the disc's polycarbonate substrate are pressed into it by a "stamper" when it is manufactured. So hundreds or thousands of identical CDs can be created from the same mold. CD-Rs (the "R" stands for "recordable") are manufactured first as blank discs and then data is later recorded on them using a laser disc burner.

High Tech High no longer sells CD-Rs or floppies to students. Teachers can optionally distribute CD-Rs and floppies.

A CD-R starts as a blank disc and is burned (recorded). A replicated disc is custom molded (like an LP). CD-Rs are normally not sold at retail.

first determine your read offset, then determine the combined read/write offset. By using this formula, you will get the write offset. Write Offset = Combined Read/Write Offset - Read Offset It has to be the same pressing like I used, as different pressings usually uses a different offset. This specific error occurs, when the track layout is different than the correct CD, e.g. one track is slightly longer (1 sector would be enough).

We've read that they last from six months to eighty years, but the shorter duration involved storage in the sun and sandpaper - not a pretty idea. We've had no trouble so far - we've had one return which was quickly remedied (and that may have been a blank disc that crept in) and another one with a glitch that we sorted out. These CD-Rs play well on all but the oldest CD player - our home player is from the mid-1990s and they play fine.

You really do not need the CD to set up the wheel. In fact, it is preferable to use the newest drivers that are always on our website. Please carefully follow the instructions that come with the drivers. They are in the "readme.txt" file that comes with them.

Intervention and Referral Services is a committee of teachers, an administrator, child study team members and the school nurse who meet every 6 weeks to discuss any students that are having difficulty in some area in school. Generally most referrals come from classroom teachers and the teachers come to speak about their concerns. The parents will always be advised if their child is to be discussed and will be invited to join the meeting.

The CD-R's color is a good guide to its longevity. The dye type matters most because dyes have different chemical compositions, and thus different life spans. The four major dye types used in CD-RS can be identified by their intrinsic color: It seems that the only dye that could have the smaller life span of 10 to 75yrs rather than up to 100yrs is the green or blue-green dye. Those CD's are acceptable for the majority of CD-R uses (routine backups and legal archival purposes).

Some new types of CDRs that support recording speeds up to 52x aren't fully compatible with old CD Writers with the "high speed" mark and fully support only those with the "ultra speed" sign. Top

CD-Rs are duplicated and are well suited for quick-turn around projects or projects requiring lower volume production. They are also excellent for publishing projects that require high quantity production of individualized data. We receive CD-Rs from our manufacturers as blank media. The data is written to the CD-Rs using a CD-R drive (writer/burner). We have the capacity to produce several thousand completed CD-Rs per day. At Saunders, all CD-Rs are recorded and fully verified.

If you want to play back CD-R and CD-RW discs that have MP3 audio files, look for a DVD player that is CD-R and/or CD-RW compatible and features MP3 decoding. You can use our DVD player comparison charts (specifically the Basic Features comparison chart) to look for such DVD player models. Here's how: (1) click on this link, (2) look for "Yes" under the "MP3" column, and (3) look for the "CD-R" or "CD-RW" designation under the "Audio CD" column.

A CD-R and CD-RW is basically a recordable CD. However, whether or not a DVD player capable of playing a regular CD can play a CD-R depends on the quality of the CD-R. Some CD-Rs recorded on higher quality CD burners can play perfectly. However, if you used a lower quality CD burner to make your CD-Rs and CD-RWs, then there's a chance they won't play. Also, a CD-RW (as opposed to a CD-R) have lower light reflection, so CD-RWs are even less likely to play.

We don't recommend any particular travel insurance, as each person's requirements and budget, and indeed home country, vary. However, former students have reported that the website squaremouth.com offers information on a good variety of different packages, and makes it easy to compare. What is the deductible, i.e. the amount you have to pay each time you use the insurance? The smaller the cash amount you have to pay before the insurance starts to cover you, the better.

Diamonds can be purchased from many sources and many different dealers, but the key is to buy from a professional jeweler. Some people like the experience of dealing with a traditional family jewelry, while others want the convenience of shopping several jewelers located together in a mall or jewelry exchange. Today, shoppers can even buy a diamond from Internet websites.

It depends on your CD Burner, but most new CD Burners can burn any type of CD's. If you are looking for quality CD's, you can't go wrong with Verbatime.

Sorry, but we want to make sure that everyone practices the routine safely. (After all, the purpose is to prevent injuries, not cause them.) So the CD is only available at the workshops at this time. We are working on an illustrated manual, however, and once it is finished we hope to offer the CD and manual together for those folks who can't make it to a workshop.

That all depends on your system and/or your bank account, but for making MP3s a CD-ROM that does dae (digital audio extraction) is a must. The speed of dae is sometimes related to, but not always correlated to the speed of your CD-ROM (i.e. Just because your 24x is faster than my 8x DOESN'T mean that either one does dae any faster than 1x)

Having both The Golden Orchard CD and The TABBS CD, I can assure all Apple II and IIgs users that they both contain a wealth of Apple II/IIgs programs, graphics, music, information and a multitude of fantastic archives of great interest and value to any Apple II and IIgs user. Apple Pugetsound Program Library Exchange ( ) is celebrating the 25th anniversary of its User Group founding by releasing the following Apple II Related CD-Rom Books: See the Apple II CD-ROM Info resource file R014CDROMIN.
