CD-RW is short form for "CD- Rewritable", in other words, a rewritable CD. The special feature of CD-RW is that the recorded sections can be cleared and reused for re-recording. Of course, users cannot rewrite the CD-RW to an infinite number of times. Typically, each CD-RW can be rewritten about 1,000 times.CD-RW discs are used just like CD-R discs. You can use packet writing on both CD-R and CD-RW, and you can use disc-at-once audio recording on both CD-R and CD-RW. Some software may handle CD-RW in a slightly different way, because you can do things like erase individual files, but the recorder technology is nearly identical.
