摘要： A floppy disk drive (FDD) capable of data transfer with a track density of, typically, 96 tracks per inch (TPI) is adapted for rewriting on a floppy disk on which data has been written on concentric data tracks by a 48-TPI FDD. The data tracks, each with a width W1, are arranged with a pitch P1 on the disk. The 96-TPI FDD has a magnetic head assembly comprising a read/write head capable of providing a data track width W2 of 0.4 W1 to 0.6 W1, and a pair of tunnel erase heads each capable of providing an erase width of (W1-W2)/1 to (P1/2-W2). The opposite edge portions of each prewritten data track on the disk are erased by the erase heads of the head assembly, with the latter successively positioned intermediate the data tracks. Either before or, preferably, after the erasure of the edge portions of the prewritten data tracks, the head assembly is positioned on the successive data tracks for rewriting thereon by the read/write head, with the erase heads maintained in operation for the complete erasure of the old data during the writing of new data.

摘要： A flexible magnetic disk drive is disclosed which has a data transducer mounted to a pivotal support beam for movement into and out of data transfer contact with the disk. When the transducer is retracted away from the disk, the support beam butts on the top plate of the disk drive casing for the reduction of the thickness of the disk drive, that is, its dimension in a direction perpendicular to the plane of the disk. A stepper motor is provided for moving the transducer across data tracks on the disk in response to external stepping pulses from a host system and to internal stepping pulses for recalibration. The application of such stepping pulses to a stepper motor control circuit is prevented when the disk is not loaded in the disk drive, in order to avoid the movement of the support beam in sliding contact with the top plate.

摘要： A magnetic disk drive is disclosed which has a disk drive motor for imparting rotation to a magnetic disk, and a head transport motor for transporting a transducer head or heads radially of the magnetic disk for track to track accessing. The disk drive motor and the head transport motor are fed from a common direct current supply terminal via first and second switching transistors, respectively, which independently control power delivery to the two motors for effectively saving power. A voltage regulating capacitor is connected only between ground and the output line of the first switching transistor for the disk drive motor. In order to prevent the flow of a surge current due to the voltage regulating capacitor upon conduction of the first switching transistor, a conduction retarder is provided which causes a gradual conduction through the first switching transistor in response to an actuating signal from host equipment controlling the disk drive. The conduction retarder takes the form of a capacitor connected between the collector and base of the first switching transistor in one embodiment of the invention, and of a time constant circuit connected between the host equipment and the base of the first switching transistor in another embodiment.

摘要： An apparatus for data transfer with a magnetic disk having a diameter of, say, 86 millimeters, having a pair of transducer heads for data transfer engagement with the opposite surfaces of the disk mounted on a turntable driven directly by a disk drive motor. In order to hold the magnetic disk exactly level on the turntable for proper data transfer contact with the transducer heads, a leveling mechanism is provided whereby at least the turntable is made adjustably movable in its axial direction with respect to the frame of the apparatus, as by the manual turn of an adjusting screw or screws. In one embodiment, the turntable is movable with a drive spindle on which it is mounted coaxially and which forms an output shaft of the disk drive motor. In another embodiment, the turntable travels with the complete disk drive motor.

摘要： A storage file for particular use with a flexible magnetic disk having a series of concentric magnetic tracks thereon, comprising a four phase stepping motor for moving a transducer head radially of the magnetic disk. The stepping motor has several sets of first, second, third and fourth phase windings arranged sequentially in the order named. A radial drive control circuit is provided which normally acts to cause energization of the stepping motor windings in a single phase drive mode to cause rotation of the rotor by discrete increments. In order to prevent the rotor from being trapped in alignment with the third phase windings, instead of being returned to the first phase windings, when the disk file is electrically turned on, the radial drive control circuit further functions to briefly energize a selected one or more of the second, third and fourth phase windings of each set, with the simultaneous or subsequent energization of the first phase windings. This makes it possible to positively return the transducer head to the outermost track zero position on the magnetic disk, for the commencement of proper data transfer therebetween, despite the unavoidable sensing errors of an optical "track zero" sensor commonly built into the device.

摘要： Several data storage devices for use with flexible magnetic disks are daisy chained to a central processing unit via a controller to be selectively driven thereby for data transfer with the magnetic disks. Each storage device has a motor control circuit for setting the magnetic disk into rotation when a corresponding DRIVE SELECT signal from the controller assumes a prescribed state for the first time after and IN USE signal common to all the storage devices has assumed a prescribed state. Further the motor control circuits sets the magnetic disk out of rotation when the DRIVE SELECT signal assumes the prescribed state for the first time after the IN USE signal has been set out of the prescribed state. Thus the storage devices are held out of operation to avoid unnecessary power consumption even after the production of the IN USE signal, until the associated DRIVE SELECT signals are applied. Moreover, once set into operation, the storage devices remain so despite changes in the states of the DRIVE SELECT signals during the production of the IN USE signal, allowing ready access for data transfer.
