Miniature disk drive with dynamic head loading

摘要

Disclosed is a disk drive information storage device having a housing and a disk means for recording and reproducing information. The disk drive information storage device utilizes a rotary actuator which includes a load beam and structure for dynamically loading a transducer into operative relationship with a surface of the disk means. The transducer is supported adjacent to one end of the load beam. The load beam includes at its outermost end a lift tab which extends from the load beam along an axis which is skewed from the centerline of the load beam, with the lift tab including a curvilinear portion. A cam assembly is provided on the housing adjacent to the edge of the disk means, the cam assembly including a cam surface positioned in operative relationship with the lift tab. In one embodiment, the housing has a first external dimension of about 51 mm. In another embodiment, the disk means has a diameter in the range of from about 45 mm to about 50 mm.
