Abstract

A shock absorption device of optical disc consists of rubber shock absorber fixed on frame of rotary shaft, circular spring being inserted at outer ring of said absorber, shock absorption support set on body frame for moving between using position and releasing position of circular spring to use rubber shock absorber selectively according to set of disc playing unit, support driving unit for driving the shock absorption support to move between use position and release position.

Description

(1) Technical field [0001] The present invention relates to an optical disc vibration damping device, in particular to the ability to selectively select a vibration damper according to the placement posture of the optical disc playback device, and the selected vibration damper can prevent the vibration damping device from damaging the optical disc in the playback device A disc vibration damping device. (2) Background technology [0002] Recently, recording and playback systems using optical discs such as CD-ROMs and CD-RWs are achieving higher speeds and higher speeds due to the rapid development of technology. However, many problems have arisen with the increase in speed and speed of the above-mentioned system. For example, when a CD-ROM is rotated at 48 times, the vibration transmitted to the main frame due to the rotation of the spindle motor is also very serious. [0003] Therefore, manufacturers of recording and playback systems for various optical disks strive to incr...
