摘要： A detection circuit in a magnetic recording and playback apparatus which uses partial response and the maximum likelihood method, in which neither the size of the detection circuit nor the power consumption increase when the partial response order n increases. In this detection circuit, in the circuit that detects a signal read out from a head, either a plurality of equalizers for different target equalization waveforms, or a single variable target equalizer is provided. A detector for the waveform output from an equalizer is connected in series with the detector. A plurality of combinations, each formed by an equalizer and a detector, is connected in parallel to the output of a filter, the outputs of the combinations of equalizers and detectors being input to a switching circuit, which is controlled by a switching control means. The switching control means controls the switching circuit so that just one of the combinations of equalizer and detectors is selected as the detector output. If a variable target equalizer, which is capable of generating two or more different types of equalization waveforms, is used as the equalizer, it is possible to reduce the number of equalizers to one.

摘要： A retracting assembly produces a constant torque, in a data zone of a magnetic disk, which is greater than static friction of a bearing for a rotary actuator. However, in a parking zone on an outer portion of the magnetic disk, the retracting assembly generates a torque which suddenly increases so that a large holding torque is obtained and a magnetic head is reliably locked.

摘要： A magnetic disk storage apparatus comprising a rotary actuator which prevents head positioning error resulting from vibration and impact. Since head positioning error is generated when the enclosure makes rotating movement due to translational vibration input due to vibration, a vibration proof mechanism consisting of a plurality of vibration proof supporting members are provided between the enclosure and frame. The plural vibration proof supporting members are disposed so that the linear moment around the gravity center of the enclosure is balanced against translational external force applied to the enclosure.

摘要： A magnetic disk storage apparatus in which a plurality of magnetic head positioners are independently driven with respect to each other. A housing having a sensor secured thereto indirectly senses mechanical vibration of a magnetic disk and issues a sense signal. The mechanical vibration is inevitably caused by a seek operation of a selected magnetic head positioner. Based on the sense signal, a compensating signal is generated in a mechanical vibration follow-up system disposed in the apparatus. The compensating signal is input to a coil of a driving motor of non-selected magnetic head positioners such that the effect of the mechanical vibration on the other positioners is cancelled. Thus, magnetic heads supported by the other positioners do not become off-track.

摘要： A spindle motor includes a permanent magnet multipolarized in a circular direction of the permanent magnet. The permanent magnet generates magnetic fluxes in a radial direction of the spindle motor. A core assembly has core pieces, the core pieces respectively including first portions are circularly arranged and face the permanent magnet via a gap, and second portions guide magnetic fluxes in parallel with a rotation axis of the spindle motor. Windings are turned around the second portions of the core assembly and have axes of the windings extending in parallel with the rotation axis of the spindle motor. A yoke magnetically couples the core pieces with each other.

摘要： A rotating support apparatus in a disk storage device is provided with a stationary shaft, ball bearings rotatably fitted on the stationary shaft, a rotatable member rotatably supported by and on the ball bearings, and buffer rings superimposed between the associated ball bearings and the rotatable member to absorb a thermal deformation of the rotatable member due to a change in a temperature. The buffer rings have a same coefficient of linear expansion as that of the material of which the rotatable member is made, and each of the buffer rings is in contact, at two points of the outer inner surfaces thereof, with the rotatable member or outer races of the ball bearings, and at one point of the inner or outer surface thereof, with the associated ball bearing or the inner surface of the hub, respectively.

摘要： A first component defines a threaded bore. A second component is kept in contact with the first component. A clamping screw penetrates through the second component and is screwed in the threaded bore. A lubricating agent film is interposed between the threaded bore and the clamping screw. The lubricating agent film is made of a macromolecular compound having a polar end group. The lubricating agent film serves to reduce the friction between the threaded bore and the clamping screw. Generation of dust is prevented when the clamping screw is being screwed into the threaded bore. In addition, the clamping screw exhibits a larger axial force at a certain amount of a fastening torque as compared with a conventional clamping screw. A larger axial force can thus be applied to hold the second component onto the first component.
