摘要： A magnetic disk drive has a housing for a 3.5 inch form factor and disk media of a diameter for a 2.5 inch form factor. The smaller disk media rotate at a high speed while consuming low electric lower and generating less heat while providing for quick access speeds. Usually, when the magnetic disk media are rotated at a higher speed, the electric power consumption and heat generation are increased because of the load increase. This problem is avoided with the use of cooling fins placed about the periphery of the disk media. Further, the smaller size disk media enable a decrease in torque loss during on-load rotation with the media, and a decrease of electric current to the spindle motor during rotation.

摘要： There is a problem that a high fitting accuracy between the table body and a chucking ring of a turntable is requested because the table body and the chucking ring are separately constituted and the chucking ring is integrated with the table body by fitting the ring to the body. The present invention relates to a disk drive comprising a turntable (47) on which an optical disk (33) used to reproduce an information signal is mounted and a spindle motor (51) to whose rotating portion the turntable (47) is set. The turntable (47) is provided with a mounting portion (47a) on which the optical disk (33) is mounted and a fitting portion (47b) to be fitted to the center hole (33a) of the optical disk (33) and having an elastic piece (14b) to be pressure-welded to the inner periphery of the center hole (33a), in which the mounting portion (47a) and the fitting portion (47b) are formed into one body.

摘要： A compact disc support structure includes a spindle motor, a carrier, a hub, and a plurality of snapping members. The carrier is combined with the spindle motor. The hub is fitted and fixed on the shaft of the spindle motor. The snapping member is received in the chamber of the hub and is provided with a protrusion protruding outward from the opening of the chamber of the hub. When a compact disc is fitted on the periphery of the hub and is placed on the carrier, the compact disc is snapped and fixed by the protrusion of the snapping member so that the compact disc can be rigidly fixed on the carrier to be rotated with rotation of the spindle motor.

摘要： A playback apparatus for a storage disc permits improved damping of vibration of the storage disc normal to the plane of the disc. The playback apparatus includes a first disc and a second disc, where the storage disc can be positioned between the first disc and the second disc. A predetermined distance is provided between the storage disc and the first disc within a predetermined area. The area and the distance are selected so that when there is vibration of the playback at apparatus approximately normal to the plane of the disc with an acceleration not exceeding a predetermined value, there results an amplitude of a resulting vibration of an outside edge of the storage disc in relation to a mid point of the storage disc which is below a predetermined value.

摘要： A positive and negative rotation gas dynamic pressure bearing comprises a stationary bearing member, a movable bearing member mounted for rotation relative to the stationary bearing member, dynamic pressure generating grooves having first and second ends and formed in one of confronting surfaces of the stationary bearing member and the movable bearing member, a self-switch valve connected to the movable bearing member for rotation therewith, and conducting holes having first and second ends and formed in the movable bearing member. During rotation of the movable bearing member in a first direction of rotation, a high dynamic pressure is generated at central portions of the dynamic pressure generating grooves, and a valve body of the self-switch valve moves toward a lower space of a valve case of the self-switch valve to close the second ends of the conducting holes. During rotation of the movable member in a second direction of rotation opposite the first direction of rotation, a high dynamic pressure is generated at the first and second ends of the dynamic pressure generating grooves so that the valve body moves toward an upper space of the valve case to close a through-bore of the valve case and to open the second ends of the conducting holes to allow air taken in by air taking holes of the self-switch valve to be supplied to the central portions of the dynamic pressure generating grooves through the conducting holes.
