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.

Abstract: A disk drive comprises a pivot cartridge and a molded plastic actuator body. The cartridge includes a shaft and has an outer surface that is generally cylindrical and includes first and second ring-shaped portions and a necked-down portion separating the first and second ring-shaped portions. The body has a bore hole with an inner cylindrical surface that is deformable to expand from a first diameter to a second diameter. Each of the first and second ring-shaped portions has the second diameter and is disposed in an interference fit with the inner cylindrical surface.
