    摘要： A disc device which includes a rotary drive mechanism for rotating a replaceable recording medium. An unbalance correcting mechanism adapted to correct unbalance is incorporated in a rotary body rotating unit in the rotary drive mechanism, and includes a holding system having a holding member for holding the rotary drive mechanism and a head having at least a reproducing function. Further included is a support member composed of resilient members, for supporting a casing and a unit holder to each other. The holding system has a natural frequency higher than 30 Hz but lower than 70 Hz, and exhibits a transmission characteristic having a lift-up degree of higher than 8 dB at a resonant point.

    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： A rotating disk type information storage apparatus includes a rotating disk for storing information, a head for writing/reading the information, a support member for supporting the head, a first actuator for moving the support member to a predetermined position on the rotating disk, and a second actuator including a movable member supported by the support member and capable of being rotated about an axis perpendicular to a recording surface of the rotating disk, and a driving force generating member for rotating the movable member. The movable member is integrated with the support member and has the head mounted thereto, in which a center of gravity of the movable member including the mounted members generally coincides with the center of rotation of the movable member. The second actuator corrects an error in a positioning of the support member and positions the head, and the movable member is not vibrated during the positioning.
