CD-Recordable (CD-R) is an optical disc drive that enables the user to create customized CD-ROM discs. Data that has been written to a CD-R disc cannot be changed (overwritten). CD-R discs can be read by any CD-ROM drive. CD-R drives are commonly used to create backup copies of program or data files, or to create duplicates of existing compact discs.
CD-Rewritable (CD-RW) is an optical disc drive that enables the user to create customized CD-ROM discs. Unlike a CD-R disc, a CD-RW disc's data can be overwritten, meaning data can be updated after it has been placed on the disc.
