Abstract
Disclosed is a disk drive information storage device which includes a disk for recording and reproducing information, the disk drive information storage device utilizing a rotary actuator, with the rotary actuator including a load beam for supporting a read/write recording element above a surface of the disk. The load beam includes at its outermost end a lift tab, with the lift tab being positioned such that a centerline of the lift tab is offset from a centerline of the load beam. The lift tab cooperates with a cam assembly to provide a dynamic head loading disk drive. The cam assembly is supported by the housing of the disk drive information storage device at a position adjacent to the edge of the disk and adjacent to the lift tab. The cam assembly in cooperation with the lift tab provides a lifting force along the centerline of the load beam. In one embodiment, the above-described dynamic head loading information storage device is provided in a housing having a footprint that includes a first dimension of about thirty-five millimeters. In another embodiment, the disk in the disk drive information storage device has a diameter in the range of from about thirty-three millimeters t…
