Maxmartt PVR-802W Game L-a-s-e-r Lens Head DVD Replacement Repair Part

$17.89
SKU B084G9FR6J

Brand: Maxmartt

Features:

  • L-a-s-e-r head move outward from center movement in the region of the Table-of-Contents, find location on the disk by emitting l-a-s-e-r, induced resistance to accept to the reflected signal output into electronic data.
  • L-a-s-e-r 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.
  • L-a-s-e-r head mainly includes l-a-s-e-r generator (also known as laser diode), semi-reflective prism, objective lens, lens and photoelectric diode.
  • When l-a-s-e-r head reads the data on disc, the l-a-s-e-r light from l-a-s-e-r generator goes through semi-reflecting prism and converges on the objective lens; lens will make l-a-s-e-r into extremely tiny points on CD.
  • Because of the reflection material on the disc, light will reflect back, through the objective lens, then illuminate on semi-reflecting prism.

Because of the reflection material on the disc, light will reflect back, through the objective lens, then illuminate on semi-reflecting prism. Since prism is semi-reflecting, light beam can not goes through it completely, but reached the photo-diode through the lens. Due to the disc surface is uneven point to record data, so the reflected light will be in different directions; 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.
