ABSTRACT:
A magnetic head/arm assembly has a suspension for an air bearing head slider that includes a single piece substantially rectangular flexure with two parallel flexible narrow fingers, a relatively stiff cross leg, and a central finger to which the slider is attached. A combined load beam-spring element is formed from a single piece and is fastened to the flexure so as to engage a load protuberance formed with the central finger. The substantially triangular load beam/spring element has flanges formed along a portion of its length to concentrate the resilient spring action at the opposite end to the flexure while providing a stiffening action along the remaining portion of its length. The stiff cross leg section of the rectangular flexure is crimped to detent the central finger to keep the attached slider parallel while allowing for the load protuberance thickness to the load beam.
