摘要： A control apparatus for a linear motor for driving a pickup of an information storage/readout apparatus with which the pickup can be moved more quickly and accurately to a desired target position. A slider for supporting the pickup is provided which is movable in a straight line. A magnetic circuit for forming a magnetic gap extends in the moving direction of the slider. A moving coil is mounted on the slider having at least a portion located within the magnetic gap. The voltage induced across the moving coil is detected to product a signal indicative of the velocity of the pickup. A velocity feedback loop feeds back the detected voltage to a driving source of the coil. The value of the feedback coefficient of the velocity feedback loop is set in accordance with the operating mode of the apparatus.

摘要： A device and method for controlling the movement of a focusing lens of an apparatus for reading an optical disk in which the focusing lens is positively prevented from striking the surface of the disk. The presence or absence of the establishment of a focus servo control mode is detected when the focusing lens is moved from a most wide position to the vicinity of the normal operative position. If the focus servo control mode is not established when the focusing lens has been moved to the vicinity of the normal operative position, the focusing lens is then moved away from the disk. Then, the focusing lens is moved towards the disk one more time, and the procedure is repeated.

摘要： A disc playing and controlling apparatus which includes a plurality of magazine type disc players. When a first disc player is operating, the apparatus controls the other disk players to find and load a disc holding the next song to be played. Before searching for the next song, the controller determines whether one player is already set in a standby position or whether the next song is located in the player currently being operated. If no player has been set for the next program, the apparatus reads the next selection from a program list and identifies which magazine contains the selected program based on a data map. The map stores each player number and magazine number in an one-to-one relation with the table of contents data for each song.

摘要： Tracking control device in which a tracking error signal for controlling the position of a data detecting point with a driving circuit is added to a warbling signal. The warbling signal is separated from an input signal to the drive means by a separating circuit and is utilized to detect and control the gain of the tracking servo loop. The application of the input signal to the separating circuit is interrupted when the data detecting point is located between tracks so that the tracking servo is stable at all times.
