摘要： A magnetic disk unit is provided which can protect internal mechanisms from external force. A cover 11 covers the outer periphery of a base 12 which supports a spindle mechanism 2 and a head positioning mechanism 5. The cover 11 is connected to the base 12 elastically to reduce the possibility that the external force directly acts on the base and to assure that the external force acting on the cover is transmitted to the base via a cushioning material, whereby the spindle mechanism and the head positioning mechanism are protected from the external force.

摘要： A disk locating actuator of a disk apparatus has a carrier member carrying a head and a curved flexible printed circuit fixed at its one end to the carrier member and at its other end to a base. Angles at which the flexible printed circuit is fixed are suitably determined so as to diminish any dynamic reacting force produced by vibration of the flexible printed circuit, thus ensuring high degree of head locating precision.

摘要： A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. A head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.

摘要： A rotary shaft is rotatably supported by a hydrodynamic fluid radial bearing and a hydrodynamic fluid thrust bearing which are excellent in shock resistance, an bearing arrangement in which vibration in a translation mode of the shaft, among vibration components caused by unbalance force exerted to the rotary shaft, is supported by the radial bearing, and vibration in conical mode is supported by the thrust bearing, magnetic fluid is used as lubrication oil, and a permanent magnet is located between the radial bearing and the thrust bearing so as to apply a magnetic attracting force between the rotary shaft and the thrust bearing so as to carry out axial positioning in order to use the magnetic disc device in an arbitrary attaching posture. With this arrangement, the magnetic disc device using such a bearing arrangement can enhance portability, thinning and antishock ability, and reduce noise and power consumption, thereby it is possible to provide a note-type personal computer with a high degree of reliability.

摘要： A magnetic disk drive which is to be used for recording and/or reproducing information, and a bearing assembly for use in the same magnetic disk drive. The bearing assembly includes two bearings of different diameters, of which a small-diameter bearing is arranged within an inner periphery of a large-diameter bearing. The two bearings are joined by means of bearing coupling members for connecting respectively inner rings and outer rings of the bearings. The small-diameter bearing is arranged within the inner periphery of the large-diameter bearing, and therefore a height of the bearing assembly can be made thinner to about one and a half times a height of a single bearing. It is therefore possible to make the magnetic disk drive smaller and thinner by employing this bearing assembly.

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).
