    摘要： A disk apparatus using a CLV method is provided in which disk apparatus a power consumption is reduced by providing a power save mode in which an operation of a head driving system is stopped during a standby state. The disk apparatus uses a constant linear velocity method by which method a recording/reproducing operation of information on a disk is performed while the disk is rotated at a variable speed so that the linear velocity of the head relative to the disk is maintained to be constant. A disk driving unit rotates the disk, and a head driving unit drives the head. A linear velocity controlling unit controls a rotational speed of the disk so that the linear velocity of the head relative to the disk is maintained to be constant. A constant rotational speed controlling unit rotates the disk at a constant rotational speed. A switching unit switches a control of the disk driving unit to be performed by either one of the linear velocity controlling unit and the constant rotational speed controlling unit. A stopping unit stops an operation of the head driving unit while the disk driving unit is controlled by the constant rotational speed controlling unit.

    摘要： A floppy disk drive is disclosed which is for use with a host system capable of connecting its own power supply to the disk drive when its operation is needed, and disconnecting the power supply from the disk drive when its operation is not needed. The disk drive includes a stepper motor for moving a data transducer from track to track on a rotating magnetic disk, and a track counter for ascertaining the radial position of the transducer on the disk by counting the stepping pulses fed from the host system to a stepper motor control circuit. In order to maintain the count of the track counter despite power suspension, the track counter is connected to a supply terminal of the disk drive via a reverse blocking diode, and a capacitor is connected between the diode and ground. The track counter is therefore fed from the capacitor when the disk drive is disconnected from the power supply of the host system. Preferably, the count of the track counter when the disk drive is disconnected from the power supply may be temporarily stored on an electrically erasable, programmable read only memory, and the stored count may be returned to and preset on the track counter when the disk drive is subsequently powered on.

    摘要： An optical disk reproducing apparatus uses a spindle motor having a low torque to reduced power consumption and manufacturing cost while maintaining a low error rate for reproduced data. The spindle motor is rotated at a constant rotational speed under a CAV control when a pick-up is moved. The rotational speed of the spindle motor is switched to a reference linear speed under a CLV control when a reproducing operation is performed. The reference linear speed is established for each of the zones of a recording area of an optical disk. The reference linear speed is determined by generating a zone clock set for each of the zones. A frequency error signal is generated by comparing the zone clock with the reproduction data so as to maintain the spindle motor at the reference linear speed determined by the zone clock.

    摘要： A flexible magnetic disk drive incorporates a system for reducing the power consumption of a disk sensor according to a power save signal which is supplied from a host system and which indicates whether the disk drive is active or inactive. The disk sensor has a switch connected in series with a resistor, the sensor switch being opened or closed depending upon whether a flexible magnetic disk cartridge is loaded in or unloaded from the disk drive. For powering the disk sensor at least when the disk drive is active, and for unpowering the same when the disk cartridge is unloaded while the disk drive is inactive, an OR gate is provided which has its output grounded via the sensor switch and the resistor, one of its two inputs connected to the power save signal line, and the other input to a circuit point between sensor switch and resistor. Thus the OR gate goes low upon unloading of the disk cartridge while the disk drive is inactive, so that there is no current flow through the resistor even though the sensor switch is then closed. Additional embodiments are disclosed.
