摘要： A suspension for a HGA includes a suspension flexure and an out trigger. The suspension flexure has a tongue region having a first flexure part in a tip portion thereof for mounting a trailing edge of a slider and a PZT mounting region for mounting PZT elements. One end of the out trigger is connected to the suspension flexure, and the other end of the out trigger has a trigger support portion which extends above the tongue region so as to support the leading edge of the slider. The structure of the out trigger is capable of stiffening the tongue region of the suspension flexure and, in turns, avoiding the deformation problem and the dimple separation problem during the manufacturing process or in vibration or shock events. The invention also discloses a HGA with the suspension, manufacturing methods of the HGA and a disk drive unit having such HGA.

摘要： Certain example embodiments described herein relate to a micro-actuator for use with an HGA and/or disk drive device. A substantially U-shaped frame may include a cavity capable of receiving a slider. The frame may include two segmented, flexible side arms and a bottom support arm at least partially defining the cavity. Each segmented side arm may have a PZT element mounted on an outer surface thereof facing away from the cavity, and each may include a lower portion proximate to the bottom support arm and an upper portion disposed at an end opposing the bottom support arm. The lower portion and the upper portion may be at least partially separated by a gap. Accordingly, micro-actuators having better resonance and servo performance, reduced difficulties associated with the slider/micro-actuator mounting process, and/or better shock performance may be provided.
