摘要： A magnetic memory device comprises: a vertically magnetic recording medium; a probe formed of an electrically conductive as well as soft-magnetic material, a pointed end of the probe faces the magnetically recording medium across a gap; a magnetic flux detecting element for detecting a magnetic flux caught by the probe, where the magnetic flux is from a data recorded on the magnetically recording medium; a vertical controller for keeping the gap constant by the use of a tunnel current flowing via said gap into the probe while a voltage is applied across the gap; and a scan mechanism for scanning the probe along the magnetically recording medium. The magnetic memory device may further comprises an exciting coil for magnetizing the probe so as to write a data in the magnetically recording medium. The probe may be recessed from the scanning position when the probe is not in operation.

This apparatus is provided with at least one lapping jig in which a workpiece is placed on the rotating top surface of the lapping plate. Further, a lapping head adapted to be able to rotate only in a direction on the lapping plate is attached to this lapping jig. This lapping head is equipped with a workpiece and at least two dummy work materials (or stock) so that these dummy works compose (as-polished) surfaces, which should be polished, together with the workpiece. Moreover, a device for detecting the remaining part of the workpiece to be lapped is provided on the workpiece. Furthermore, this lapping apparatus is configured so that a detection signal, which represents the detected remaining part of the workpiece and is outputted from the rotating lapping head, is sent to and a correction signal is sent from a control unit to the lapping correction device through a slip ring. A workpiece is polished while rotated on the lapping plate. Thus, the polished surface of the workpiece is kept in good condition.

摘要： A rotary actuator for positioning magnetic heads in a disk drive, comprising a stator assembly and a rotor assembly. An arm assembly having magnetic heads are fixed to the rotor assembly, which rotates back and forth within a limited angle range around a fixed axis of the rotary actuator due to the forces between plural magnets and driving current which flows though flat coils. Two flat coils are aranged on an arcuate inner surface of the stator such that two adjacent vertical parallel portions thereof closely contact with each other. Two flat coils have an electrical connection with a driving source that the currents through the two adjacently parallel portions flow in the same direction. Three permanent magnets are disposed on the rotor surface, the central magnet having a greater lateral width than that of other two side magnets, and a polarity of the central magnet is opposite to that of other magnets. In another embodiment, each of flat coils comprises an inner coil and an outer coil resulting in enhancing the torque of the rotary actuator. Several modifications of coil and permanent magnet arrangement, and other related improvements in the structure thereof are also disclosed.

摘要： According to one embodiment, in a disk drive, a voice coil motor is controlled to cause a head to minutely vibrate in a radial direction on a track of a disk. When the voice coil motor vibrates the head in the radial direction of the disk, frictional force occurring between the disk and the head is calculated based on the driving force of the voice coil motor generated to vibrate and detected positional information, thereby measuring frictional characteristics.

摘要： A receiver receives an acoustic wave in an atmospheric pressure measuring apparatus. Since a variation in the intensity of an acoustic wave reflects a variation in the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver. The atmospheric pressure can in this manner easily be measured with a simplified structure.

摘要： A flying head slider includes a write head element and a read head element mounted on the slider body. A first transformable actuator serves to protrude the write head element toward a recording medium. A second transformable actuator serves to protrude the read head element toward the recording medium. The first and second transformable actuators can separately be controlled. The amount of protrusion can thus be individually controlled for the write head element and the read head element. The flying height can individually be set above the surface of the recording medium for the write head element and the read head element. Such an adjustment of the flying height enables the write head element and the read head element to simultaneously get closest to the recording medium.
