2.3 Sled Servo Block
The moving of pick-up is controlled by tracking servo output through a low pass filter.
The sled kick voltage is outputted for track jump operation.
Figure 17. Sled servo block
2.4 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.
