摘要： A head loading system including a head support mechanism supporting heads for at least reproducing information in juxtaposed relation to a recording medium, and a loading actuator driving the head support mechanism to move the heads toward and away from the recording medium. The loading actuator include motion converting arrangement for converting a linear motion of a solenoid into a rotary motion which is capable of increasing the amount of motion when the linear motion is converted into the rotary motion, thereby enabling the loading actuator to drive the heads with a small amount of linear motion. The motion converting arrangement includes a rotary member connected to a plunger of the solenoid and formed with grooves, a frame juxtaposed against the rotary member and formed with grooves and a bearing fitted between the grooves. The linear motion of the plunger is converted into a rotary motion of the rotary member by the action of the bearing performed in cooperation with the grooves.

摘要： A positioning method and apparatus for precisely positioning a magnetic head on a desired track of a magnetic disc includes stepping motor having a plurality of stationary pole windings adapted to be rotated stepwise, and a mechanism for moving the magnetic head by a rotational movement of the stepping motor. By rotating the stepping motor stepwise by an integral multiple of the number of stationary pole windings of the stepping motor, the magnetic head is moved by one track width of the magnetic disc. By driving the stepping motor by the integral multiple of the number of stationary windings, the magnetic head is positioned by the same stationary pole windings without being affected by an assembling tolerance of the stationary pole windings. The stepping motor may also be driven so as to overrun a desired track by at least one step and then rotated in a reverse direction by the same number of steps so that a positioning error due to forward and reverse rotations of the stepping motor is eliminated.

摘要： A disk drive housing structure has a rotating disk for recording information and a transducer adapted to write and read information on and from the disk. The structure further includes a positioning system having at least an arm to which the transducer is fixed and which is adapted to selectively position the transducer along the radial direction of the disk transducer by turning the arm. The structure also includes a member on which the disk, transducer and positioning system are mounted, wherein the mounting member includes a first housing which supports thereon both ends of a rotary shaft of the recording medium and both ends of a rotary shaft of the positioning system, and which has a first aperture part. The first housing further includes a second aperture part through which the disk and the rotary shaft supporting the disk are inserted and to which a supporting member for the rotary shaft of the recording medium is fixed.

摘要： First and second magnetic heads, or magnetic head sliders containing these heads, which are brought into contact with a magnetic disc on its both sides so as to record and reproduce information signals, are respectively supported by first and second swing arms. The first and second swing arms are respectively supported by first and second elastic bodies. The swing arms are respectively provided with first and second adjusting screws for adjusting the movable range of the swing arms. The first adjusting screw operates to adjust the pressure of a first spring supported by the first arm and the position of the first magnetic head. The second adjusting screw operates to locate the associated second magnetic head to a position which is adjusted to the thus-adjusted position of the first magnetic head.

摘要： A method of adjusting the position of a magnetic head in a magnetic head positioning mechanism positions the magnetic head at a target track on a magnetic disk. Since a floppy disk system is so designed as to make a floppy disk replaceable, it is necessary to adjust accurately the position of the magnetic head from the position of a spindle. According to the present invention, the position of the magnetic head is adjusted by the method wherein the displacement of an amount of deviation from a prescribed track in the magnetic head positioning mechanism is calculated beforehand, the amount of deviation is sampled subsequently by moving the magnetic head, this sampled amount of deviation is compared with the aforesaid calculated displacement to know the maximum and minimum values of the amounts of deviation on the track of movement of the magnetic head, and the adjustment is implemented on the basis of these values.

The arrangement includes a speed detection circuit for detecting a relatively low rotational speed of the disk and a control circuit for speeding up the disk to a higher rotational speed for the read/write operation in response to the detection of the lower disk speed, whereby the disk is protected from damage by being rotated at the lower speed when its center hole is held between the collet and spindle.

摘要： Increased memory capacity for a magnetic disk device is realized without degrading information error rate, by making the number of sectors at a given circumference of the disk variable in accordance with a radial direction of a disk. The number of sectors is made variable by deciding a predetermined information error rate from a ratio of reproduced signal output to noises of head, disk and amplifier at a maximum recording and reproducing frequency at a certain radial position along a disk.
