ABSTRACT:
A lead structure adapted for attachment to a metal disk drive head suspension of the type having a mounting region on a proximal end, a head-receiving flexure on a distal end, a rigid region and a spring region between the rigid region and the mounting region. The lead structure is formed from a laminated sheet of material and includes a copper conductor layer and a stainless steel base layer bonded together by a polyimide insulating layer. The conductor layer includes a plurality of transversely spaced, elongate electrical conductors adapted to extend between the flexure and mounting region of the head suspension. The metal base layer includes flexure mounting, rigid region mounting and mounting region mounting sections having tabs which are adapted to be welded to the head suspension. At least portions of the conductor layer which traverse the flexure and spring regions of the head suspension are free from the metal base layer.
