Abstract
A trace suspension assembly for supporting a smaller head slider from an actuator arm in a disk drive includes a flexure formed in three layers, a stainless steel layer for mechanical strength, a polyimide layer for electrical isolation and a ductile copper layer for electrical transmission. The copper layer is etched to form a plurality of U-shaped and contiguous circuit traces beginning at the distal end of the flexure and running symmetrical along each side of the flexure to its proximal end. Indentation sites along the copper traces adjusts for pitch static attitude and/or roll static attitude errors.
