Optical axis inclining mechanism

Abstract

An adjusting mechanism of light axle tilt consists of a screw set with high adjustment ability at back fixing seat of subaxle guide lever and two screw sets with high adjustment ability at fixing base plate of main axle motor. It works as adjusting screw set at subaxle guide lever first to make optical read - write head base plate be almost to true plane and then adjusting screw set at fixing base plate of main axle motor to make plane of disc carrying tray be parallel to each other with plane of optical read - write module base plate.

Description

Technical field: [0001] The invention relates to an optical axis inclination adjustment mechanism, and in particular to an adjustment mechanism for adjusting the incident inclination angle of laser light of a read-write head, which is applied in an optical disk drive. Background technique: [0002] With the vigorous development of information technology, the speed and quantity of information accumulation are far beyond the past. Therefore, storage media is also playing an increasingly important role in information technology. [0003] Optical storage media, such as LD (Laser Disc), DVD, and VCD, have gradually become important storage media in the market because of their large amount of stored data and low manufacturing cost. For optical disc drives that read these optical storage media, in order to read or write data more quickly, the optical read-write head needs a higher read rate. [0004] One of the important factors to improve the reading rate of the optical read-wri...

AI Technical Summary

Problems solved by technology

However, when the above-mentioned design is actually produced and tested, the optical read-write head of some optical disc players still cannot completely make the laser light hit the data area of ​​the optical disc at a vertical angle.
