Inventor: IGARASHI TAKAYUKI
IPC: G11B17/04
Filed: 1997-09-29
Abstract: A disc drive includes a disc drive main body having a playback or recording/playback mechanism of a disc and a disc tray which is constructed to support the disc thereon and is movable with respect to the disc drive main bodybetween a disc eject position and a disc loaded position; and a motor provided in the disc drive main body for moving the disc tray, wherein the moving speed of the disc tray is variable by changing the number of rotations of the motor. The motor is driven by rectangular pulses from the motor driver, in which the numberof rotations of the motor is varied by changing the on/off widths of the rectangular pulses so that the moving speed of the disc tray is reduced in a stepwise mannerover the period from the start to the stop of the disc tray movement. This enables to realize a high speed movement of the disc tray without increasing theload to be imposed on the disc and the loading mechanism and the like with the use of a relatively small gear ratio in the rotational speed reduction mechanism, which results in easy operation of the emergency eject mechanism and the manual loading mechanism.
