Abstract

Official abstract text for this publication.

A novel suspension assembly includes a suspension assembly mounting plate, a microactuator mounting structure extending from the suspension assembly mounting plate, a load beam extending from the microactuator mounting structure, and a laminated flexure attached to the load beam. The laminated flexure includes a tongue that has a read head bonding surface. The suspension assembly includes a stainless steel surface having a gold coating, and a piezoelectric microactuator attached to the microactuator mounting structure and electrically connected to the gold coating.

First claim

1 - 28 . (canceled) 29 . A disk drive comprising: a disk drive base; a spindle attached to the disk drive base; a disk mounted on the spindle; a coarse actuator attached to the disk drive base, the coarse actuator including an actuator arm; a suspension assembly, the suspension assembly including a suspension assembly mounting plate attached to the actuator arm; a microactuator mounting structure extending from the suspension assembly mounting plate; a load beam extending from the microactuator mounting structure; and a laminated flexure attached to the load beam, the laminated flexure including a tongue; wherein the suspension assembly includes a stainless steel surface having a gold coating, and further comprises a microactuator attached to the microactuator mounting structure and electrically connected to the gold coating; and a read head bonded to the tongue, wherein the load beam includes at least one hinge plate and the stainless steel surface is a stainless steel surface of the hinge plate. 30 . A suspension assembly comprising: a suspension assembly mounting plate; a microactuator mounting structure extending from the suspension assembly mounting plate; a load beam extending from the microactuator mounting structure; and a laminated flexure attached to the load beam, the laminated flexure including a tongue that has a read head bonding surface; wherein the suspension assembly includes a stainless steel surface having a gold coating, and further comprises a microactuator attached to the microactuator mounting structure and electrically connected to the gold coating, wherein the load beam includes at least one hinge plate and the stainless steel surface is a stainless steel surface of the hinge plate. 31 . The suspension assembly of claim 30 wherein the at least one hinge plate and the load beam are a single component having material continuity rather than being an assembly of subcomponents. 32 . The suspension assembly of claim 30 wherein the at least one hinge plate is attached to the load beam by a plurality of spot welds. 33 . A head gimbal assembly (HGA) comprising: a suspension assembly, the suspension assembly including a suspension assembly mounting plate; a microactuator mounting structure extending from the suspension assembly mounting plate; a load beam extending from the microactuator mounting structure; and a laminated flexure attached to the load beam, the laminated flexure including a tongue; wherein the suspension assembly includes a stainless steel surface having a gold coating, and further comprises a microactuator attached to the microactuator mounting structure and electrically connected to the gold coating; and a read head bonded to the tongue, wherein the load beam includes at least one hinge plate and the stainless steel surface is a stainless steel surface of the hinge plate.
