ABSTRACT:
In one embodiment, a rigid disk drive including a rotary actuator having a lift tab extending asymmetrically from the end of the load beam which supports a slider with read/write element is disclosed. The free end of the lift tab cooperates with a cam surface on a cam assembly to provide dynamic loading and unloading of the slider while imparting a roll to the slider as it is loaded to and unloaded from the disk. In another embodiment, the lift tab extends from the end of the load beam along an axis generally parallel to the longitudinal axis of the load beam, but the axis of the lift tab is offset from the longitudinal axis of the load beam. In a further embodiment, a disk drive including a rotary actuator having a load beam which includes a lift tab extending from the free end, with the lift tab cooperating with a cam assembly which is located adjacent to the edge of recording media, but not extending over a surface of the media is provided.
