Abstract
A flexure for attachment to a load beam in an integrated lead disk drive suspension assembly. The flexure includes a spring metal layer having slider mounting region, a first surface and a second surface opposing the first surface. A first group of conductive leads extends along at least a portion of the first surface and is separated from the spring metal layer by a first dielectric layer. A second group of conductive leads extends along at least a portion of the second surface and is separated from the spring metal layer by a second dielectric layer. A conductive interconnection extends between a conductive lead from the first group of conductive leads and a conductive lead from the second group of conductive leads. One or more leads from each of the first and second groups of conductive leads can be attached to a magnetic head.
