1. Introduction This document describes Toshiba's XM-7002B CD-ROM Drive. This drive reads digital data stored on CD-ROM and CD-Audio discs. The CD-ROM disc is single sided and 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 digital data stored on CD-ROM discs at maximum 24 times faster rotational speed. This drive is a new generation drive with highest performance such as 95 ms (targe

3.3.4. Vibration detection (1) This drive detects vibration which occurs when unbalanced disc is played, and rotation speed of two steps (16X, 10X) is selected according to the vibration level and the rotation speed is dropped automatically. It is necessary to mount the drive stably in PC to detect the vibration correctly. (2) This drive was tuned up to detect the vibration on the assumption that the drive was mounted in Toshiba DynaBook Satellite Pro 440 series. Mounting condition in Toshiba
