ABSTRACT:
A disk drive head suspension assembly for supporting a head slider over selected tracks of a rotatable data storage disk. The suspension assembly includes a load beam having proximal and distal ends and a bearing cover portion. A gimbal on the distal end of the load beam includes a flexure pad having a slider-engaging first surface and a second surface opposite the first surface. A ball-receiving hole extends through the flexure pad. A ball is mounted in the ball-receiving hole. The ball has a load point portion which extends from the second surface of the flexure pad and engages the bearing cover portion of the load beam. A static attitude compensating portion of the ball extends from the first surface of the flexure pad. A head slider is bonded to the slider-engaging first surface of the flexure pad by a layer of adhesive. The static-attitude compensating portion of the ball is engaged with the head slider and the adhesive fills spaces between the slider and the first surface of the flexure platform to hold the slider at a desired static attitude.
