ABSTRACT:
A rotary microactuator-based head-gimbal assembly design controls the unwanted deflection of a flexure in a data storage device and eliminates hinge deformation. The head-gimbal assembly maintains the co-planarity of the hinged islands in the microactuator under the applied load acting on the flexure and two associated hinged islands. The dimple post is placed at the dimple loading region of the flexure tongue and has the same height as adhesive dams on paddles secured to the hinged islands. The dimple post is formed by branching one of the existing conductive traces covered by a photoresist layer to the dimple loading region on flexure tongue. In an alternative embodiment, the dimple post is secured to the dimple loading region of the flexure tongue by means of adhesives with a variety of viscosity and elastic moduli.
