摘要： Embodiments of the invention decrease bending vibrations and torsional vibrations of a voice coil generated by off-plane vibrational forces on the voice coil to reduce noise and to enable a large capacity. In one embodiment, a rotating disk type storage unit comprises a rotating disk recording medium, a head that moves radially relative to the rotating disk recording medium to perform recording or reproduction, a turnable actuator having mounted on one side thereof the head, and a voice coil motor to drive the actuator. The voice coil motor comprises a voice coil mounted on the other side end of the actuator, and a magnet arranged in opposition to the voice coil. A magnet outer periphery of the magnet disposed distant from an actuator turning center is formed to be arcuately concave in shape, and the concave-shaped outer periphery intersects the voice coil.

摘要： A magnetic disk apparatus capable of reducing deformation of a magnetic disk is disclosed. The magnetic disk apparatus comprises a magnetic disk on which data is recorded while the disk is driven, a hub around which the magnetic disk is supported from an under side of the magnetic disk, and a clamp in contact with the other side of the magnetic disk and fixing the magnetic disk. An O-ring is interposed between a flange formed at an outer circumference of the hub and the magnetic disk, and a spacer is interposed between the magnetic disk and the O-ring. Thus an upper surface of the hub is in contact with an under surface of the clamp and defines a vertical position of the magnetic disk.

摘要： In a magnetic disc apparatus, it is hard to fix a pivot mechanism in a carriage, in view of a mounting space, and in the case that a casing is made of resin, it is hard to fix in accordance with a conventional screwing method in view of a rigidity and a strength. A pivot mechanism (107) is fixed to a base (100) by press fitting a plastically deformable pivot pin (108) of the pivot mechanism (107) to the base (100), passing the pivot pin (108) through a sleeve (107-a) of the pivot mechanism (107) and plastically deforming the pivot pin (108). In the case of dissembling, the pivot pin (108) is pushed out from the base (100) together with a carriage (104), and thereafter the pivot pin (108) is separated from the pivot mechanism (107). Only the pivot pin (108) is disposable.

摘要： Embodiments of the invention provide an actuator head suspension assembly having an efficient voice coil. In one embodiment, a voice coil is formed in a circular or any other shape than the conventional sectorial shape to increase the efficiency of the voice coil and diminish oscillation and noise of an actuator head suspension assembly. The voice coil shape is selected such that the proportion of an out-of-plane force becomes smaller than that in the conventional sectorial voice coil and the proportion contributing as weight to the oscillation energy also becomes smaller.

摘要： A first parameter correlated with a degree of a variation in the output from the air-fuel ratio sensor is calculated. A possible range of a second parameter representing a degree of a variation in air-fuel ratio among the cylinders is determined based on the first parameter. The first parameter is calculated with an air-fuel ratio of a predetermined cylinder forcibly changed. A difference between the unchanged first parameter and the forcibly changed first parameter is determined. A first characteristic representing a relation between the second parameter and the difference is determined based on the possible range of the second parameter and the difference. One of the determination value and the first parameter calculated before the forced change is corrected based on inclination of the determined first characteristic.
