磁盘存储器磁头伺服定位机构一般如图1所示。其驱动电机是直线电机,径向运动位置传感器是由伺服盘和伺服磁头以及位置信号电路构成。实际上国外在略早一点的磁盘机中位置传感器是光栅或同步感应器。国内伺服磁盘盘面图案的刻制尚未解决,因此位置传感器一 Disk storage head servo positioning mechanism generally shown in Figure 1. The drive motor is a linear motor, the radial movement of the position sensor is composed of servo and servo head and position signal circuit. In fact, a little earlier in the disk drive position sensor is a grating or synchronous sensor. Servo disk disk pattern design has not been resolved, so the position sensor
