Patent ID: 7253993

Claim:
A head slider with a precise positioning actuator, comprising: a thin plane shaped head section provided with a first surface that is substantially perpendicular to an air bearing surface of said head slider, a second surface opposite to said first surface, side surfaces perpendicular to said first and second surfaces and at least one head element formed on said first surface; and an actuator section for precisely positioning said at least one head element, said actuator section including a) a pair of movable arms capable of displacing its top end portions in response to a drive signal applied to said actuator section, both of said side surfaces of said head section being fixed to said top end portions of said pair of movable arms, b) a base to be fixed to a support means of said head slider, said pair of movable arms extending from said base along said air bearing surface wherein the base and pair of movable arms form a U-shape, and c) a static part coupled with said base between and spaced from said pair of movable arms to form an E-shape and the static part spaced from the head section, each movable arm comprising an arm member made of zirconia and a piezoelectric element formed on or fixed to a surface of said arm member.
