    • During the access mode of a movable magnetic head in a disk file, a program of position control signals is derived from a simulator, the input of which is clocked at sector time intervals. The position control signals of the simulator are periodically transferred to the summing point of a servo loop which successively is error conditioned, dependent on the subsequent nominal magnetic head positions derived from the simulator. Servo sectors on the data disk are sampled by the magnetic head, evaluated and converted to a digitally coded position error signal. The error signal is summed with a digital position control signal, and the output sum signal in analog form is applied to the motor that drives the head. The track following function is accomplished by means of a closed servo loop, which is also used in the access mode.
    • 在磁盘文件中的可移动磁头的访问模式期间,从模拟器导出位置控制信号的程序,模拟器的输入以扇区时间间隔计时。 模拟器的位置控制信号被周期性地转移到依赖于从模拟器导出的随后的标称磁头位置的伺服回路的求和点,该伺服回路依次进行误差调节。 数据磁盘上的伺服扇区由磁头采样,被评估并转换为数字编码的位置误差信号。 误差信号与数字位置控制信号相加,模拟形式的输出和信号被施加到驱动磁头的电机。 轨道跟随功能通过闭合伺服回路来实现,该循环也用于接入模式。

    • For the servo track control of magnetic heads over magnetic tracks, in addition to the main servo position signals arranged in offset fashion to the middle of the track, auxiliary servo position signals are provided symmetrically on each side of the middle of the track. These auxiliary servo position signals are offset along the track length relative to each other and are smaller than half the track width. In the determination of the position error signal, they serve to indicate the tilting of the magnetic head relative to the recording track in that they are unequal. If the magnetic head deviates greatly from the middle of the track, these auxiliary servo position signals can be added to the main servo position signals to obtain a stronger position error signal. For determining and compensating uniform disturbance variables, the momentary values of a control signal are measured and a mean value is formed thereof which, at predetermined intervals, is added to a preceding mean value, stored, and entered as an additional control signal to the control path.
    • 对于通过磁迹的磁头的伺服轨道控制,除了以跟偏移方式布置在轨道中间的主伺服位置信号之外,辅助伺服位置信号对称地设置在轨道中间的每侧。 这些辅助伺服位置信号相对于彼此沿轨道长度偏移并且小于轨道宽度的一半。 在确定位置误差信号时,它们用于指示磁头相对于记录轨道的倾斜,因为它们不相等。 如果磁头从轨道中间大大偏离,则这些辅助伺服位置信号可以添加到主伺服位置信号,以获得更强的位置误差信号。 为了确定和补偿均匀的扰动变量,测量控制信号的瞬时值,并且形成平均值,其以预定的间隔被加到前一个平均值上,作为附加控制信号存储并输入到控制器 路径。
