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 117 extends from the end of the load beam 114-1 along an axis generally parallel to the longitudinal axis 177 of the load beam 114-1 but the axis 178 of the lift tab 117 is offset from the longitudinal axis 177 of the load beam 114-1.
