A Study of the Servo-systems on the Rulling Machine for Optical Discs

This paper describes several precision control systems of the servorulling and pre-formatting machine. They are the spindle servo, the microfeed carriage drive, the focus servo and the laser control. This paper also describes the way of clock operation, the rulling experiments on the optical disc and their results, it is showed that the accuracy of track pitch is 1.6μm+0.1μm.
