track-following servo system
磁道跟踪伺服系统
In the moving head disc unit, the closed loop feedback control system in which the head positioning mechanism is controlled by means of track positioning signal recorded on the servo surface for seeking tracks. The system is composed of servo surface, servo head, head positioning mechanism and servo control circuit to reduce the deviation of seeking track and realize the high accuracy positioning of the head density.
在移动头磁盘机中，利用伺服盘面上记录的磁道位置信息来控制磁头定位机构寻找磁道的闭环反馈控制系统。它由伺服磁盘、伺服磁头、磁头定位 机构和伺服控制电路等部分组成，能减少寻道偏差，实现高精度的磁头定位。 |
