1. Introduction This document describes TOSHIBA's SR-C8002 CD-R/RW Drive. 2. Features SR-C8002 reads digital data stored on CD-ROM media and CD-Audio discs. The CD-ROM media has a 12 cm or 8 cm diameter. It typically contains approximately 20 600 MBytes or 200 MBytes of information respectively. (1 MByte=2 Bytes) This drive reads CD-ROM media at maximum 24 times faster rotational speed. This drive is a new generation drive with highest performance such as 120 ms access Time. This drive write

Equipment (1) When mounting the equipment, use four M2-P0.4 tapping holes located on the left and right sides of the equipment. (2) The opposite surface of the bearing surface (fitting surface when mounting) of the tapping holes must be kept flat so that the bearing surface can be fit evenly. (3) Use the mounting screws which do not enter deeply inside the equipment more than specified value.
