CDRW: A CDRW drive is a drive that can not only read CD's, but can also write to blank CD media. Blank CD media comes in two varieties: CDRW and CD-R, The difference being, CDRW disks can be written to and erased several times, where as CD-R disks can only be written to once and then the data becomes permanent. CDRW disks are good to use for data backups or copying things you're not sure you want to keep, but aren't good for music because most audio CD players will not recognize them. CD-R disks are good for all of the above as well as music because a wide variety of CD-ROMs and Audio CD players will read them without a problem, and they're also very cheap making them almost dispensable if something happens to them. .
