Later, when the CD-R is played back, the CD-R is now actually a CD-ROM. (A few CD players may have difficulty reading CD-R discs, but playback problems are usually caused by scratches, poorly applied or too-heavy off-center CD labels, and discs that have been exposed to heat or UV light - discussed below.) CD players read CD-R and CD-ROM discs equally well in almost all cases. You have probably heard of several types of CD-ROM discs, including those that contain music, software, video, photos, and games. On each of these types of CD-ROMs, the data is formatted differently. CD players are made to be able to read or decode each of these CD-ROM formats so you can easily use the disc, without knowing much about its contents. CD-R discs can be burned in the same formats as CD-ROMs, and played the same simple, easy way.

Therefore CD-Rs are sometimes called "write-once" discs. There are also erasable "re-writable CD-RW" discs. CD-RW discs are sometimes called "write-many-times" discs, and can be fully erased and re-written up to 1,000 times. Unlike CD-Rs, CD-RWs cannot be played by most CD players. They are for data storage and editing uses in computers. We discuss CD-RWs in detail under question #12 below. (2) What do disc "write speeds" mean? (32X, 40X, 48X, 52X, etc.)ĬD-R discs are described by their recording capacity or runtime length. You can buy both 74-minute and 80-minute CD-R discs. Today most CD-Rs are sold in 80-minute lengths, but you will see some brands that offer both 74 and 80 minute sizes. The actual cost of making the discs is about the same. However, some of the very old CD burners do not recognize the 80-minute CD-Rs, so the short 74-minute discs are still offered by some makers. Both of the discs are the same physical dimensions or measurements - 120mm (12cm) in outside diameter, with a 21mm center hole.ĬD-Rs are also described by their write-speed certification. A 2X speed means that the disc can be BURNED or recorded in 1/2 the length of the disc total runtime or 40 minutes for an 80-minute disc, an 8X disc at 1/8 the runtime, or 10-minutes - on down to as little as 2 minutes or less at 48X speeds!ĬD-Rs are tested and certified by their factories to be properly recordable at the rated speed. Today's fastest write-speeds are usually 48X, but 52X rated discs are also available. The most popular write speed purchased in today's market is the 48X rated CD-R (2004). Today's fastest rated discs can burn at up to 52x speeds on 52x capable writers.
