Abstract: This paper describes the application of afrequency-locked servo system in the control system ofa laser cutting machine of optical disks for servogrooves and pre-formatted information. The stability ofthe angular velocity of the spindle is up to 5 $MUL10$+$MIN@6$/ and the accuracy of the track pitch is 1.6$mu@m $POM 0.03 $mu@m. !2
