Abstract

A slider and a microactuator element are disposed on a gimbal portion of a flexure. The gimbal portion comprises a metal base, an electrically insulating resin layer, a conductor disposed on the resin layer, an electrically insulating adhesive block, and an electrically conductive paste. The adhesive block secures an end portion of the microactuator element to the metal base. The conductive paste is provided between the conductor and an electrode of the microactuator element. A first adhesive interface extending along the thickness of the resin layer, a second adhesive interface extending along a surface of the resin layer, and a corner portion are formed between the metal base and the conductive paste.

First claim

What is claimed is:

1. A disk drive suspension comprising:
a load beam;
a flexure comprising a stationary part secured to the load beam and a gimbal portion on which a slider is disposed; and
a microactuator element mounted on the gimbal portion,
wherein the microactuator element comprises an element body, which comprises first and second end surfaces, and an electrode covering at least one of the end surfaces of the element body, and
wherein the gimbal portion comprises a…
