Paper Abstract

This paper describes the application of a frequency-locked servo system in the control system of a laser cutting machine of optical disks for servo grooves and pre-formatted information. The stability of the angular velocity of the spindle is up to 5 X 10-6 and the accuracy of the track pitch is 1.6 micrometers +/- 0.03 micrometers .
