Whats the difference between CD-Rs and CD-RWs?
Nearly all 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. So if you make a mistake while recording a CD-R — for example if you change your mind about song order — you can’t erase or re-record the disc. The CD-RW designation indicates a “rewritable” disc — you can erase and re-record on the same disc over and over again. CD-RW blanks actually use a different technology and disc material, so they may not play back on some older players.
