激光光盘伺服槽及预制格式刻划机控制系统研究与设计

本文描述了激光光盘伺服槽及预制格式刻划机的主轴回转。直线微进给、自动调焦、激光控制等精密控制系统,对光盘预格式化进行了理论研究。主轴回转稳速精度达到5×10^-6,刻槽螺距精度达到1.6μm±0.03μm。

Study and Design of Control System of Laser Cutting Machine of Optical Disk for Servo Grooves and Preformed Information

This paper describes several precision control systems of laser cutting machine of optical disk for servo grooves and preformed information.They are the spindle servo,the microfeed carriage drive, the focus servo and the laser control.The paper also describes how to record preformed information on optical disk.It is obtained that the stability of angular velocity of spindle up to 5×10^-6 and the accuracy of track pitch is 1.6μm±0.03μm.
