    摘要: Disclosed herein is a rotary actuator having a retractor mechanism which can retract magnetic heads to a CSS zone of magnetic disks only by a mechanical bias force in stopping a magnetic disk drive at any cylinder position of the heads. The rotary actuator includes an actuator arm assembly rotatably mounted on a base of the magnetic disk drive, an FPC mounted on one side surface of the actuator arm assembly, and a magnetic circuit constituting a voice coil motor by combination with a moving coil supported to the actuator arm assembly. A retractor plate is fixed to the actuator arm assembly at a position opposite to a mounting position of the FPC with respect to the center of rotation of the actuator arm assembly. The retractor plate functions to retract the magnetic heads to the CSS zone of the magnetic disks by magnetic reaction with a magnetic flux in the magnetic circuit.

    摘要: 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.
