Patent ID: 8325446

Claim:
A disk drive comprising: a disk drive base; a disk rotably mounted to the disk drive base; an actuator rotably mounted to the disk drive base, the actuator including at least one actuator arm and a flexible printed circuit (FPC) that includes a plurality of electrically conductive FPC bond pads; and at least one head gimbal assembly attached to the at least one actuator arm, the at least one head gimbal assembly comprising a read head that includes a write coil and a magneto-resistive read element; and a suspension assembly that comprises a load beam, and a laminate flexure that comprises a structural layer, a dielectric layer, and a conductive layer, the laminate flexure including a tongue portion that connects to the read head and a flexure tail that extends to the plurality of FPC bond pads; wherein the flexure tail includes a first plurality of flexure bond pads in electrical communication with the write coil, each of the first plurality of flexure bond pads being aligned with a corresponding one of the plurality of FPC bond pads, and a second plurality of flexure bond pads in electrical communication with the magneto-resistive read element, each of the second plurality of flexure bond pads being aligned with a corresponding one of the plurality of FPC bond pads; wherein each of the first plurality of flexure bond pads includes a widened region of a corresponding one of a first plurality of electrical traces in the conductive layer; and one of a first plurality of discontinuous islands in the structural layer; wherein each of the second plurality of flexure bond pads includes a widened region of a corresponding one of a second plurality of electrical traces in the conductive layer; and one of a second plurality of discontinuous islands in the structural layer; and wherein a first width of at least one of the first plurality of discontinuous islands is greater than a second width of at least one of the second plurality of discontinuous islands.
