description A head gimbal assembly for a disk drive includes a flexure tail terminal region having flexure bond pads in electrical communication with the head. Each of the flexure bond pads includes a widened region of a corresponding one of a plurality of electrical traces in a conductive layer, and a discontinuous bond pad backing island in a structural layer that overlaps the widened region. The flexure tail terminal region also includes a plurality of discontinuous edge stiffener islands in the structural layer that do not overlap the widened region of any flexure bond pad, and that are disposed no more than 50 microns from one of the two opposing longitudinal outer edges of the flexure tail terminal region. At least one of the plurality of discontinuous bond pad backing islands is disposed no more than 50 microns from one of the two opposing longitudinal outer edges.
