摘要
本文介绍了光盘的结构,阐述了光盘存储和读取信息的机理及光学拾音头的自动聚焦和寻迹的原理,并就激光器、探测器等光电子器件的特性和光盘系统的容量等有关问题作了讨论。
In this paper, the structure of compact optical disk will beintroduced, and the mechanism of storing and ectracting informationfrom it and the principle of automatically focusing and tracking thedick of the optical pick-up will be elaborated. The related questionthe opto-electronic devices such as laser, detective, etc., and thecapacity to store information of the compact optical dick systemswill be discussed too.
