摘要： A thin film piezoelectric element includes a piezoelectric thin film layer, a seed layer and an elastic substrate layer. The piezoelectric thin film layer is a laminated structure comprising a first electrode layer, a second electrode layer and a piezoelectric layer sandwiched between the first electrode layer and the second electrode layer. The seed layer is formed on the second electrode layer, and the elastic substrate layer is formed on the seed layer. The thin film piezoelectric element is a single layer structure and has an elastic substrate layer for supporting the single layer structure, thereby it has enough stiffness and flexibility to afford facilities for manufacture and assembly and to avoid film peeling and deformation, ultimately increasing the production efficiency and lowering the cost. The invention also discloses a method for manufacturing the thin film piezoelectric element, a head gimal assembly and a disk drive unit with the same.

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.
