    Abstract: Disclosed is a magnetic disk apparatus constructed to reduce a track positional deviation of a magnetic head. This magnetic disk apparatus includes a rotary mechanism for rotating the magnetic disk and a rotary type actuator, provided with the magnetic head at its front end, which magnetic head has a write head and a read head, for moving the magnetic head in such a direction as to traverse tracks of the magnetic disk by making rotations about a rotary shaft. A distance A from the center of rotation of the rotary type actuator to the magnetic head is set equal to or larger than a distance B from the center of rotation of the rotary type actuator to the center of rotation of the magnetic disk. Even when separating a write element and a read element, the track positional deviation of the magnetic head can be reduced. This magnetic disk apparatus includes an enclosure accommodating both of a rotary mechanism and the rotary type actuator and having a base taking such a configuration that one side surface thereof is opened and a cover fitted in the base, wherein a side for separating the base and the cover is formed at a slant to a long side of the apparatus. This construction makes it possible to enhance a rigidity of the enclosure and reduce the track positional deviation of the magnetic head.

    Abstract: A rotary driving apparatus controls the generation of vibration and noise due to high speed rotation, to realize high accuracy rotation, so that a storage apparatus such as a disk drive can have high speed rotation and improved storing density on its recording medium. The apparatus includes a fixed shaft for rotatably supporting a rotor, a bearing fitted between the shaft and the rotor, at least two projections projecting from the surface of the shaft, and a stator coil mounted on the projections. The projections absorb stator vibration, and isolate the head, the storage disk and other parts from the stator vibrations. A gap area is formed between the stator coil and the shaft to dampen vibrations created by the stator. The gap may be filled with vibration-absorbing material.
