    摘要： In a flexible disk drive having a main frame in which a flexible disk is inserted and a direct-drive motor having a stator disposed on a main surface of the main frame and a rotor including a permanent magnet, a gap between the main surface of the main frame and the permanent magnet is set at a distance so that the rotor does not fall due to gravity by attracting the rotor to the main frame by the magnetic attractive force of the permanent magnet even if the rotor is turned upside down to the stator.

    摘要： In an FDD control apparatus for controlling a floppy disk drive for driving a floppy disk loaded in the floppy disk drive, a counter (34) produces a target track position signal indicative of a target track position for magnetic heads in response to an external seek direction signal and an external step signal. A counter (35) is activated when the floppy disk is loaded in the floppy disk drive to generate an internal step signal. When the floppy disk is loaded in the floppy disk drive, a counter (33) is put into an active state to produce a current track position signal indicative of an actual current track position for the magnetic heads in response to a selected seek direction signal and a selected step signal. A comparing circuit (36) compares the target track position signal with the current track position signal to produce a coincidence signal and an internal seek signal.

    摘要： In an integrated circuit for use in controlling a flexible disk drive for driving a flexible disk loaded therein, a power on reset circuit produces a reset signal after a predetermined time duration elapses where a power supply voltage is stable from a time when a power supply is applied. The power on reset circuit comprises a voltage detecting circuit for detecting a power supply voltage to produce a voltage detected signal and a delay circuit for producing, responsive to the voltage detected signal, the reset signal after the predetermined time duration elapses. Disposed between a selectable function circuit and a logic circuit, an output holding circuit holds output signals of the selectable function circuit as held signals and supplies the held signals to the logic circuit. The output holding circuit consists of two D-type flip-flops which are disposed in correspondence with two output signal lines of a logical circuit.

    摘要： In a floppy disk driver controlling circuit which is for use in controlling a floppy disk driver including a stepping motor (23) and which comprises a stepping motor driver (21) for producing a driving current to drive the stepping motor and a control section (22) for controlling the stepping motor driver, each of the control section and the stepping motor driver includes CMOS transistors as switching transistors. A combination of the control section and the stepping motor driver is formed as a single CMOS integrated circuit (25). The stepping motor driver produces the driving current between 80 mA and 250 mA, both inclusive, to drive the stepping motor when the stepping motor has a diameter which is substantially equal to 15 mm.

    摘要： In an index signal generator for generating an index signal for use in a direct-drive motor having a rotation axis and comprising a stator and a rotor, a particular at least one of M magnetized elements is used as an index detection magnet having magnetic force which is different from those in remaining ones of the M magnetized elements. Wound around one of a specific one of particular three cores in the stator, an index detection coil detects variations of the magnetic force generated by the ring-shaped permanent magnet to produce a detected signal. On the basis of the detected signal, the index signal is generated.

    摘要： A motor rotatably driving a flexible disk has a rotor having an external peripheral side surface on which an index detection magnet is mounted. A main circuit board mounts a control circuit for carrying out a driving control of the motor and extends in a direction perpendicular to a rotation axis of the motor. Attached to the main circuit board, a sub circuit board extends in a direction in parallel with the rotation axis of the motor at a position close to the external peripheral side surface of the rotor. Mounted on the sub circuit board, an index detection Hall element has a magnetic field detection surface which is disposed so as to oppose to the external peripheral side surface of the rotor.
