Problems solved by technology

[0011] However, in the shape of the chassis, the vertical wall 101 of the corner notch is close to the rotating surface of the optical disk, and the rotation of the optical disk will disturb the flow of air, which may cause abnormal noise.
[0012] However, simply reducing the coverage area of ​​the vertical wall may weaken the mechanical strength of the chassis and cause the noise generated by the disc rotation itself to leak out, so there is a problem of increased noise.

Abstract

The inventioin relates to an optical disk apparatus, in a prior art slim-type high speed rotation optical disk apparatus, the side wall of the bottom chassis is bent at a bending point toward the side of the optical disk according to the configuration of the corner air window section of the chassis. According to the present invention, this bent side wall is formed so as to have a first vertical wall which is adjacent to the bending point and a second vertical wall which is adjacent to and lower than the first vertical wall. This constitutes an L-shaped vertical wall in the air window section of the bottom chassis, resulting in reduced noise.

Description

Technical field [0001] The present invention relates to an optical disc device, and particularly relates to a thin-shaped form suitable for mounting on a notebook personal computer or the like, which can reduce noise or vibration even when a motor is rotated and driven. Background technique [0002] In the prior art, as devices for reading and writing digital information, optical disk devices such as CD drive devices and DVD drive devices have been widely used. [0003] In particular, with the popularity of notebook personal computers (hereinafter referred to as "notebook PCs") in recent years, the weight of the device itself has become lighter and the number of production units of the type in which the optical disc is placed on the turntable has tended to increase. [0004] In addition, in such optical disc devices, with the development of optical disc technology for recording and reproduction, the storage capacity thereof tends to increase. Because of this, in order to achieve hig...
