SLED SERVO BLOCK
The moving of pick-up is controlled by tracking servo output through a low pass filter.
The sled kick voltage is output for track jump operation.
Figure 14. Sled Servo Block
SPINDLE SERVO BLOCK
The 20K
resistor and 0.33uF capacitor form the 200Hz low pass filter, and the carrier component of spindle servo
error signals is eliminated. In CLV-S mode, SMEF becomes "L" and pin 25 low pass filter fc lowers, strengthening
the filter further. The characteristics of high frequency phase compensation in focus tracking servo and the
characteristics of cut off frequency in CLV low pass filter are tested by FSET pin.
