Abstract
A head suspension assembly for supporting a head slider from an actuator arm in a disk drive includes a load beam having a flexure tongue configured with a static offset error correction protuberance which extends from the slider-engaging surface of the flexure tongue. A load point dimple extends from the distal end of the load beam at a location spaced longitudinally along the axis of the HSA from the flexure tongue and from the static offset error correction protuberance, for engaging and applying a load to a head slider mounted to the flexure tongue. The static offset error correction protuberance and the load point dimple together function to reduce and/or eliminate static pitch offset error and static roll offset error.
Claims11
A suspension for supporting a head slider from an actuator arm in a disk drive, the suspension including:
- a load beam having a distal end and a proximal end;
- a base on the proximal end of the load beam, for mounting the suspension to the disk drive actuator arm;
- a flexure tongue resiliently extending from the distal end of the load beam, the flexure tongue including:
- a head slider-engaging surface configured for mounting to a head slider;
- and
- a static offset error correction protuberance extending from the head slider-engaging surface;
- and
- a load point dimple extending from the distal end of the load beam at a location spaced from the flexure tongue and the static offset error correction protuberance, for engaging and loading a head slider mounted to the flexure tongue;
- wherein the load point dimple and the static offset correction protuberance are spaced from one another along a longitudinal axis of the load beam.
