Description
[PRODUCT PRINCIPLE]:Lens move outward from center movement in the region of the table-of-Contents,find location on the disk by emitting,induced resistance to accept to the reflected output into electronic data..[DATA READING FEATURES]:Game 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 deal with drive inside..[PRODUCT CONFIGURATION]:Lens mainly includes generator,semi-reflective prism, objective lens,lens and photoelectric diode.Due to the disc surface is uneven point to record data, so the reflected light will be in different directions..[EFFECT OF USE LENS]:When head reads the data on disc,the light from generator goes through semi-reflecting prism and converges on the objective lens.Lens will make into extremely tiny points on CD..[WORKING PRINCIPLE]: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.
