光盘驱动器电学系统设计与实验

光盘驱动器是光学、电学与机械部件的组合件，为完成其正常读写，驱动器中的电学系统设计十分关键．重点讨论光盘驱动器中LD驱动器电路、RF前置放大电路与伺服前置放大器电路的设计与实验．设计的APC电路具有静电击穿和浪涌电流保护以及电源故障防护功能，有效地保证了LD的安全使用．

The Design and Experiment of Electronic System of Optical Disk Driver

The optical disk driver is an assembly of optical, electronic and mechanical parts. In orderto accomplish the normal read-write operation, the electronic parts design is very important. Designand Experiment of a driver circuit of LD, RF forward amplifier circuit and servo forward amplifier circuit for the optical disk driver are discussed emphatically. Since APC circuit is designed with protections against electrostatic breakdown, surge current and power source fault, the safe operation of LDcan be effectively guaranteed.
