Abstract
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.
