摘要： In magnetic disk structure having a high density, positioning errors (generally referred to as "flutter error") occur due to fluctuation (i.e., flutter) of a magnetic disk. As a result reading precision deteriorates. This is a significant problem in realizing a large capacity providing magnetic disk apparatus. This can be resolved by magnetic apparatus such that a suspension which holds a slider having a magnetic head at one end and which is attached to a supporting arm at the other end is inclined so that an interval between the suspension and the magnetic disk is small on the inner rim side and is large on the outer rim side with this arrangement the occurrence of the positioning error due to the fluctuation of a deformation of the magnetic disk is reduced, thereby enabling a high density recording of the magnetic disk.

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 carriage in a position control mechanism using an access mechanism of a magnetic disk device or a linear motor is supported linearly movable in parallel to a positioning reference plane on a stationary side by means of a carriage support mechanism. The carriage support mechanism is composed of support units rigidly engaged with the carriage or the stationary side and support units elastically engaged with the carriage or the stationary side. The rigidly and elastically engaged units are selectively arranged so that the carriage is prevented from being inclined by thermal deformations due to the heat generation caused upon the driving of the carriage.
