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 method for incorporating a disk medium into a magnetic disk drive, in which the rotation center of the disk medium when a servo track information is written onto the disk medium (STW) coincides with the rotation center thereof when the disk medium is incorporated into the disk apparatus. A reference marker is provided as a positioning reference on a part of the disk medium. The disk medium is incorporated into a STW apparatus so that STW is performed on the disk medium. The disk medium is also incorporated into the magnetic disk drive in such a manner that a distance from an axis of rotation center of the disk medium to the reference marker is the same as when the STW was performed onto the disk medium.

摘要： A rotary moving coil actuator in a disk drive selectively positions a read/write head with respect to disk medium. A carriage is pivotable about an axis and has a carriage arm for supporting the head. A pair of magnets, disposed in spaced relationship within a magnetic yoke structure, have spaced flat faces perpendicular to the axis and define a gap therebetween. A flat coil structure, comprising one or a pair of flat coils, is attached to the carriage and disposed at least in part within the gap between the opposing flat faces of the magnets so as to be movable along a stroke of movement relatively thereto. The flat coil structure in cooperation with the magnets, generates a driving force in a direction approximately parallel to a first line which is perpendicular to the axis and passes through the axis and toward the read/write head and thereby substantially perpendicular to the seek direction of the head.

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 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： This invention relates to a head position control method for a disk device that uses a disk medium whose tracks have been formatted externally, and a disk device that effectively uses the range of motion of an actuator. In a disk device that has a disk medium, a head, an actuator, a control circuit, there is a conversion mechanism that sets a data area in the writing range of the disk that corresponds to the range of motion of the actuator, and converts a logical address to a physical address in the data area. This invention makes it possible to set a storage capacity that makes maximum use of the range of motion of the actuator for any device, even when there is a position offset in the range of motion of the actuator.
