摘要： Disk storage devices have exhibited an increase in rotational vibrations which attend high speed rotation due to weight unbalance of a disk. Accordingly, an unbalance correcting mechanism, provided with correcting balls to correct the aforesaid unbalance, meets a problem that the correcting balls are made unstable at the time of low speed rotation to generate vibrations and noises. A disk drive device is provided with an unbalance correcting mechanism comprising an annular-shaped groove provided in a turntable on a spindle motor and a plurality of correcting balls received in the groove, and in which a sliding resistance member is provided on a bottom surface of the annular-shaped groove to suppress a sliding resistance of the correcting balls on the sliding resistance member, and a correcting ball motion auxiliary member is provided on an inner peripheral side wall of the groove (toward an axis of rotation).

摘要： There is provided a disc drive by which the fluid loss of a disc is reduced and the electric power consumption of a spindle motor can be decreased. In the disc drive according to the present invention, a rotation load reducing member is provided between a top cover and the disc. The rotation load reducing member is movably supported by a clearance adjustment member. While the disc is rotating, the rotation load reducing member is moved in the direction approaching the disc. Thereby, the thickness of an air layer on the upper surface of the disc is decreased.

摘要： Since a disc vibrates in a natural mode at a predetermined rotation speed, a variation in a tilt of the disc relative to an optical head is caused. As a result, the read/write performance of a disc drive is deteriorated. The disc drive has a disc tilt database for recording a relative tilt angle of the disc in a tangential direction thereof associated with the disc natural mode and the disc rotation speed at which such tilt occurs, a circuit for detecting a disc rotation speed, and a tilt drive circuit. An objective lens is tilted so that the relative tilt angle is corrected, and thus, stable read/write performance of the disc drive is achieved.
