摘要： A HGA of the invention includes a slider, a micro-actuator with PZT elements, and a suspension for supporting the slider and the micro-actuator. The slider has a leading edge, a trailing edge opposite to the leading edge, an air-bearing surface connecting the leading edge and the trailing edge, and a slider mounting surface opposite to the air-bearing surface. The micro-actuator is positioned between the slider and the suspension with the PZT elements facing the slider mounting surface. The slider further has a transition surface connecting the leading edge and the slider mounting surface. The transition surface is recessed into the slider, so the transition surface is not easy to hit the PZT elements, thus the shock performance of the HGA is improved. The invention also discloses a manufacturing method of the HGA and a disk drive unit having such an HGA.

摘要： A micro-actuator includes a metal frame having two side arms, a top support arm and a bottom support arm respectively connected with the top ends of the two side arms. The two side arms are in parallel with and spaced from each other a distance adapted to hold a slider therebetween that is mounted on the top support arm. An isolation layer is coupled with each side arm of the metal frame; and a piezoelectric element is bonded with the isolation layer. When operating the micro-actuator, an electric sparking problem will not occur for existence of the isolation layer. The invention also disclose a method of manufacturing the micro-actuator, a HGA and disk drive unit with the micro-actuator.
