Abstract
A precise positioning actuator to be fixed to a head slider provided with at least one head element, for precisely positioning the at least one head element includes a base, and a pair of movable arms extending from the base and having slider fixing portions to be fixed to side surfaces of the head slider at top end sections thereof. Each of the pair of movable arms includes an arm member and an actuator layer formed on a side surface of the arm member, for displacing the arm member in response to a drive signal applied thereto. The actuator layer is terminated on the side surface of the arm member at a frontward position form the slider fixing portion.
Claims11
A head device including a head section formed in a thin plate shape and provided with at least one head element, and a precise positioning actuator section integrally fixed to said head section for precisely positioning said at least one head element, said actuator section comprising:
- a base;
- and
- a pair of movable arms extending from said base and having head fixing portions fixed to side ends of said head section at top end sections thereof, each of said pair of movable arms including an arm member and an actuator layer formed on a side surface of said arm member and along a side surface of said base to induce a force for displacing said arm member in response to a drive signal applied to said actuator layer, said actuator layer being terminated on said side surface of said arm member at a position short from said head fixing portion.
