ABSTRACT:
A suspension assembly which can be energized to provide in-situs fly height adjustment for a head of a disc drive or energizable to adjust preload force for CSS. The suspension assembly includes a shape memory flexure element having an energizable length differential. In one aspect, the flexure element is integrated with a flexible suspension circuit which provides advantages for manufacture and assembly. In another aspect, the flexure element is coupled to a bending portion of the head suspension assembly and energized to adjust flexure of the suspension assembly relative to the bending portion.
