    • A system for detecting an off-track amount of a present head position with respect to a normal position of a desired track on a disc in a disc storage unit in which a closed loop control is employed to control the position of a magnetic head. A repetitive pattern is stored as reference information in each reference information region on the disc in such a way that it is deviated in the longitudinal direction of a track from the repetitive patterns stored in the adjacent regions. When the reference information in the two adjacent regions is read out by the head, a ramp signal whose gradient is varied in accordance with the position of a desired track is generated in synchronism with the readout of the reference information. The ramp signal is used as a threshold value and the numbers of the repetitive pattern signals obtained from the signals read out from the reference information in the two adjacent regions which are in excess of the threshold value is counted. Then, in accordance with the difference between the two counted values thus obtained from the two regions, an off-track amount of the head position from the normal position of a desired track is detected.
    • 一种用于检测相对于盘存储单元中的盘上的期望轨道的正常位置的当前头位置的偏离轨迹量的系统,其中采用闭环控制来控制磁头的位置。 将重复图案作为参考信息存储在盘上的每个参考信息区域中,使得其沿轨道的纵向方向从存储在相邻区域中的重复图案偏离。 当头部读取两个相邻区域中的参考信息时,与参考信息的读出同步地生成根据期望轨道的位置来改变其斜率的斜坡信号。 将斜坡信号用作阈值,并且从超过阈值的两个相邻区域中的参考信息读出的信号中获得的重复图案信号的数量被计数。 然后,根据从两个区域获得的两个计数值之间的差异,检测从期望轨道的正常位置开始位置的偏离轨迹量。

    • Lead wires are extended from phase coils of a head control motor, so that their effective reactances may be varied, and reactance selection circuits are additionally provided to switch values of the reactances of the phase coils to a low value. A vector position is sequentially delivered to phase current generators by a processor for designating the vector position, so that a head is displaced to a desired position. Thereafter, the reactances of the phase coils are switched to a high value by the reactance selection circuits, and then the vector position corresponding to the normal one is applied to the phase current generators, so that the head is so controlled as to be positioned at its normal position on a track on a disc and is maintained at this position. During the time of displacement of the head across the tracks, it is ensured that the head control motor is driven at a high response speed.

    • An optical frequency filter for selectively blocking or transmitting an amplitude-modulated optical signal. In a first embodiment of the invention, an optical coupler adds two optical inputs. The output of the optical coupler is delayed and attenuated and then applied to the input of an optical splitter. One output port of the optical splitter is applied to one input port of the optical coupler, with the optical signal to be filtered applied to the other input port of the coupler. The filtered output signal is produced at the second output port of the splitter. In a second embodiment, the delay and attenuation are performed between the output of the splitter and the input of the coupler. In a third embodiment, the signal to be filtered is applied to the input port of an optical splitter. One of the output ports of the splitter is coupled through a delay to one input port of an optical combiner, while the other output port of the splitter is delayed and coupled to the other input port of the coupler.
