Patent ID: 8879212

Claim:
A disk drive comprising: a disk drive base, an actuator pivotably attached to the disk drive base, the actuator including an arm; and a head gimbal assembly (HGA) attached to the actuator arm, the HGA including a head, and a suspension assembly that comprises a load beam and a laminated flexure attached to the load beam, the laminated flexure including: a structural layer having a head mounting tongue to which the head is bonded; a first conductive layer including a first plurality of interleaved traces, and a second conductive layer including a second plurality of interleaved traces; a first dielectric layer disposed between the structural layer and the first conductive layer; and a second dielectric layer disposed between the first conductive layer and the second conductive layer; wherein the first plurality of interleaved traces includes at least a first conductive trace and a second conductive trace separated by a first lateral intertrace spacing, and the second plurality of interleaved traces includes at least a third conductive trace and a fourth conductive trace separated by a second lateral intertrace spacing; and wherein the fourth conductive trace overlies the first lateral intertrace spacing and the first conductive trace underlies the second lateral intertrace spacing.
