4 4 CARRIAGE SERVO SYSTEM

The carriage servo system inputs the TRKG actuator's drive

voltage, and through the carriage servo EQ shown in Fig.

4-20, the amount required for the carriage movement is ob-

tained.

Also, the carriage's LOCATE operation obtains LOCATE

voltage by switching over the internal current source in the

serial data. This voltage is about 6V. However, during

startup and lock, since the output current is limited to

200mA, the voltage will become lower than 6V.
