Problems solved by technology

[0014] However, when rotating the current 52x speed CD for playback / recording, if the disc is rotated too fast, there is a problem that it is difficult for the clamping device to fix the disc
[0015] In order to solve the above problems, as long as the magnetic force of the magnet is strengthened, the force to fix the disc can also be increased. However, in the reverse operation, in the process of moving the disc, it takes a lot of force to lower the turntable and break away from the clamping device, so it is difficult remove disc
[0016] Therefore, the design of the turntable and the clamping device needs to achieve the strongest force to fix the disc within the range that does not affect the up / down movement of the chassis when moving the disc, but it is difficult to meet this condition at high speeds

Abstract

Disclosed optical drive comprises following parts: turntable including holes located at two sides of noses in use for being inserted to central holes on optical disk; pieces of center of circle located at place corresponding to holes located at two sides of noses on turntable; springs in use for supporting the said pieces of center of circle; magnets setup at inner side of the noses on turntable; clamping arms in inner oblique shape corresponding to noses. In time of playing and recording optical disk at high speed, the disclosed optical drive is capable of preventing oscillation phenomenon of optical disk.

Description

(1) Technical field [0001] The invention relates to an optical disc drive, in particular to an optical disc drive which prevents the optical disc from vibrating when playing or recording the optical disc at a high speed. (2) Background technology [0002] The so-called optical disc is a product that uses optical properties to record and play information, and is generally in the shape of a small disc. In order to use an optical disc, an optical disc drive is required, and an optical pickup provided inside the optical disc drive is used to read or record information on the optical disc. [0003] Optical discs can be typically divided into two types, CD and DVD, but they can be divided into many types according to different recording methods. CDs include CD-ROMs manufactured by molds, CD-Rs that can be recorded once, and CD-RWs that can record information repeatedly. DVD includes: DVD-ROM, DVD-R, DVD-RW, DVD-RAM and other discs. However, the biggest difference between CD and...
