FLB FSET FRCH Figure 15 Focus servo block 27 2 2 Tracking Servo Block During detection of defect the tracking error signal is outputted through the tracking servo loop after passing the low pass filter formed by connecting a capacitor 0 1uF and a built in 470KQ resistor to the TDFCT pin pin57 in case of tracking phase compensation The value of tracking gain up down can be controlled by TGU TG2 pin The peak frequency of tracking loop phase compensation the dynamic range and offset of opamp can be adjusted by changing the value of resistor connected to FSET pin same as focus loop In case of unstable status of actuator after jumping the ON OFF of tracking loop is controlled by TM7 switch of break circuit After 10 track jumping servo circuit gets out of the liner range and actuator s tracking becomes occasionally unstable Hence unnecessary jumping with many tracking error should be prevented TRACKING COMPENSATION FSET Figure 16 Tracking servo block 28 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
