About Optical Pick-Up Laser Lens PVR-802W Game Laser Lens

1. Laser head move outward from center movement in the region of the Table-of-Contents, find location on the disk by emitting laser, induced resistance to accept to the reflected signal output into electronic data; 2. Laser head is a the essential part of CD drive, and also is the most sophisticated part.It is mainly used for data reading, so take special care when cleaning drive inside; 3. Laser head mainly includes laser generator (also known as laser diode), semi-reflective prism, objective lens, lens and photoelectric diode; 4. When laser head reads the data on disc, the laser light from laser generator goes through semi-reflecting prism and converges on the objective lens; lens will make laser into extremely tiny points on CD; 5. Because of the reflection material on the disc, light will reflect back, through the objective lens, then illuminate on semi-reflecting prism; 6. Since prism is semi-reflecting, light beam can not goes through it completely, but reached the photo-diode through the lens; 7. Due to the disc surface is uneven point to record data, so the reflected light will be in different directions; 8. People define different direction of signal as "0" or "1", light-emitting diodes gets the data of "0", "1", and ultimately resolve them as the data we need.
