Ling Yan. Study and Design of Control System of Laser Cutting Machine of Optical Disk for Servo Grooves and Preformed Information[J]. Editorial Office of Optics and Precision Engineering, 1991,(2): 69-71DOI:
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
