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

DVD-ROM
DVD-ROM drives, 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.
