[0002] Laser head is mainly responsible for the reading of data, so it is particularly careful when cleaning the inside of the optical drive. Laser head mainly includes: laser generator (also known as laser diode), half-reflective prism, objective lens, lens and photodiode. When the laser head reads the data on the disc, the laser emitted from the laser generator transmits through the half-reflective prism, converges on the objective lens, and the objective lens focuses the laser into extremely small light spots and hits the optical disc. The reflecting material on the optical disc will reflect the incoming light back, and then it will be transmitted through the objective lens and hit the half-reflective prism. At this time, since the prism is a half-reflective structure, the light beam will not completely penetrate it and return to the laser generator.

[0003] Laser head is a precision component, and it is inevitable to encounter failure problems during use. In addition, the precision component needs complicated process during inspection, thereby increasing the detection time, and the laser head inspection is usually taken by human, which makes the fingerprint or force too large, resulting in damage to the laser head and affecting the subsequent use effect.
