N101内部的循迹伺服逻辑电路的功能是将FZC:TZC、MIRR、ATSC、DFCT等各种检测信号进行逻辑编辑和处理,由巡检开关送至N102中的伺服定序器,将各种检测信号(包括FOK信号)送至N106,输出的DATA数据信号.通过N102中的CPU接口送到伺服定序器,输出DATA数据信号。控制N101内部的循迹伺服逻辑电路.输出各种控制指令。控制循迹误差形成电路的3个平衡开关BAL1～BAL3,3
The function of tracking servo logic circuit inside N101 is to logically edit and process various detection signals such as FZC: TZC, MIRR, ATSC, DFCT, etc., and sent to the servo sequencer in N102 by the inspection switch, The signal (including FOK signal) is sent to N106, the output DATA data signal is sent to the servo sequencer through the CPU interface in N102 to output the DATA data signal. Control the tracking servo logic inside N101. Output various control commands. The control track error forming circuit balance switch BAL1 ~ BAL3,3
