US 2007/0165332 A1 · Actuation device and method for high density hard disk drive head

Abstract

A disk drive apparatus. The apparatus has a first drive device and a support member coupled to the first drive device. The support member has a tongue portion and a gimbal portion. The tongue portion is coupled the gimbal portion. A fixed drive device is formed within a first portion of the tongue portion. A movable drive device is operably coupled to the fixed drive device and formed within a second portion of the tongue portion. A read/write head is coupled to the movable drive device. A voltage source is coupled between the fixed drive device and the movable drive device to cause movement of the read/write head by forming an interaction between the fixed drive device and the movable drive device.
