The Tm7 Switch is a Brake Switch which turns the Tracking Loop On/Off when the Actuator is unstable after a
Jump. After the Servo has jumped 10 tracks the Servo Circuit is out of the liner range, and sometimes the Actuator
follows an unstable track. So this prevents unnecessary jumping caused by unwanted Tracking Errors. Tg2 and
Tgu blocks adjust the Tracking Servo Loops high frequency Gain. It adjusts the gain of the wanted frequency band
zone through the external Cap.
SLED SERVO
This servo integrates the Tracking Servo output to move the pick-up. Also, during Track movement, it outputs Sled
Kick voltage for the Track Jump along the Sled axis.
