ABSTRACT:
The disk includes a disk recording surface, and the ramp includes a ramp. A head stack assembly of a hard disk drive includes an actuator arm and a suspension assembly attached to the actuator arm. The suspension assembly includes a first elongated region having a distal region and a planar surface for facing toward the disk recording surface; the first elongated region defines a longitudinal axis. The suspension assembly includes a second elongated region positioned adjacent to the distal region. The second elongated region includes a lift tab for engaging the ramp surface and is vertically offset from the planar surface such that the lift tab is vertically displaced further from the disk recording surface than the planar surface. The second elongated region further includes a curved lift tab supporting member for supporting the lift tab and positioned between the distal region and the lift tab. The lift tab supporting member includes a first region integrally formed with the distal region, a second region integrally formed with the lift tab, and a third region positioned between the first and second regions such that the second region is vertically offset from the first region. The third region defines a first trough for stiffening the supporting member. The distal region and the first region define a second trough for stiffening the distal and first regions. The second trough extends along the direction of the longitudinal axis and has an outer surface for facing toward the disk recording surface, the outer surface being vertically displaced closer toward the disk recording surface than the planar surface.
