DVD-ROM Drive

Each Infinia™ Model 7220 comes equipped with a Toshiba SD-M1002 DVD-ROM Drive.
DVD (Digital Versatile/Video Disc) is a new digital video decoding technology that uses the
variable bit-rate MPEG2 compression to provide enhanced video, audio, and multimedia
capabilities. This drive reads digital data stored on CD-ROM, DVD-ROM, and CD audio
discs. Maximum storage capacity is 4.38 GB for single layers/single sided disc and 15.9 GB
for duel layered/double sided disc. Because of the high storage capacity and data transfer rate
(1350 KB/sec), these drives are capable of storing and reading high quality and long duration
MPEG2 moving picture data. Additionally, the drive reads data stored on CD-ROM at up to
8X and supports Revision 2.6 of ATAPI.
