Abstract
A head gimbal assembly (HGA) for a disk drive includes a load beam, a laminated flexure attached to the load beam, and a head attached to the laminated flexure. The laminated flexure includes a tail for electrical connection between the head and a flex cable of a head stack assembly. The laminated flexure tail may include a plurality of conductive traces, a structural layer, and a dielectric layer there between, and may be disposed partially within a slot of an actuator arm. A first insulative cover layer is disposed on the plurality of conductive traces. A plurality of stand-off islands is disposed on the first insulative cover layer, and over at least one of the plurality of conductive traces (e.g. the writer traces). At least one of the plurality of stand-off islands is at least partially disposed between the first insulative cover layer and the inner slot surface.
