CD-RW
CD-Rewritable(CD-RW)drives, standard on some models, enable the recording and reuse of CD recordable media. The laser used in CD-RW has variable temperatures to provide the three functions of CD-RW drives: playing CDs or CD-RWs, erasing CD-RWs, and recording CD-RWs.
CD-RW drives can read traditional CDs, but many older CD players cannot read CD-RWs. Their light reflective properties are about one-third that of traditional CDs. CD-RW drives cannot read DVDs.
To learn more about CD-RW drives, see the Understanding Your Personal Computer publication for your personal computer model and type number. This publication is available on the World Wide Web at http://www.ibm.com/pc/support.
DVD-ROM
DVD-ROMdrives, standard on some models, differ from CD-ROM and CD-RW drives as the result of refinements in laser technology.
The recording tracks on DVD media are not as deep and are more condensed than on CDs or CD-RWs, therefore DVDs provide more storage space. DVD media also use both sides of the disk, as opposed to just one side for CDs and CD-RWs.
DVD-ROM drives read traditional CDs, CD-RWs, and DVDs.
