Abstract

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.
