Abstract
A suspension for a HGA includes a suspension flexure and an out rigger. 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 rigger is connected to the suspension flexure, and the other end of the out rigger has a rigger support portion which extends above the tongue region so as to support the leading edge of the slider. The structure of the out rigger 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.
