摘要： A drive control system for a linear motor having a stator and a sliding member capable of sliding along the stator. A position detector comprises an arrangement of light emitting elements and a detector, or the converse to produce a position signal. A comparator compares the position signal with a reference signal to produce an output drive signal for the linear motor.

摘要： PURPOSE:To surely make a large quantity of track jumps in a short time, by detecting the prescribed state of vibrations caused by wobbling in accordance with tracking error signals and generating jump driving signals in response to the detection. CONSTITUTION:A comparator 13 detects a prescribed state of vibrations caused by wobbling as the sine wave change of the relative position of an information reading point and recording track in the radial direction of a disk and a controller 11 outputs a jump driving signal through a differentiation circuit 12 in response to the detected output. The jump is performed by means of an actuator composed of a driving coil 8 and tracking mirror 9 when the vibration reaches the vicinity of the outermost peripheral section and the speed becomes slow and, simultaneously, an analog switch 6 is turned off and a servo loop is opened. When a tracking error signal reaches zero thereafter, a positive jump signal is outputted from the controller 11 and, simultaneously, the switch 6 is turned on and the servo loop is closed, and then, the information reading point is pulled to the adjacent track.

摘要： PURPOSE:To execute a smooth shift to tracking driving by detecting a descent completion to a record disk surface of a needle tip at a pickup cartridge whose descent is started by an output of an intermusic detector, by a tracking error detector. CONSTITUTION:A pickup arm 2 provided with a pickup cartridge 1 on the tip part is supported so as to be displaceable by an arm holder 3, and attached to the lower part of a carrier 4. The carrier 4 is moved linearly along guide bars 6a, 6b by a linear motor. An intermusic detector is provided in the vicinity of the cartridge 1, and a tracking error detector for detecting a relative displacement of the arm 2 and the holder 3 is provided in the vicinity of a rotation supporting point of the arm 2. Also, a moving speed of the carrier 4 is detected by a generator. A system controller lowers the needle tip of the cartridge 1 by an output of the detector, and when a window comparator detects the descent exactly, a changeover switch S is switched to a fixed contact, and the pickup arm is driven smoothly.
摘要翻译：目的：通过跟踪误差检测器，通过检测在通过音频间检测器的输出开始下降的拾取盒上的针尖的记录盘表面的下降完成来执行跟踪驱动的平滑移位。构成：在前端部设置有拾取盒1的拾取臂2被支撑以便能够被臂保持器3移动，并且附接到托架4的下部。托架4沿着导杆6a线性地移动，6b由线性电动机。在盒1附近设置有一个音频间探测器，并且在臂2的旋转支撑点附近设置用于检测臂2和保持器3的相对位移的跟踪误差检测器。而且，移动载体4的速度由发生器检测。系统控制器通过检测器的输出降低盒1的针尖，并且当窗口比较器精确地检测到下降时，切换开关S切换到固定触点，并且拾取臂被平稳地驱动。
