Abstract:
1. A head gimbal assembly including a head slider with at least one head element, a precise positioning actuator fixed to said head slider for precisely positioning said at least one head element, and a support for supporting said actuator, said actuator comprising a pair of movable arms capable of displacing in response to a drive signal applied to said actuator, said head slider being mounted between said pair of movable arms, said head slider and said actuator being adhered by at least one adhesive films wherein a spacing between said moveable arms at a base of said actuator is larger than the width of the head slider so that an air gap exists between said movable arms and said head slider with said movable arms deformed such that a space between them will gradually narrow toward a top end sections of the movable arms such that only the top end sections of said movable arm members are adhered to side surfaces of said head slider using said at least one adhesive film so that said movable arms will not come in contact with said head slider so as to limit the movement of the actuator in operation.
