Abstract
An HGA includes a head slider with at least one head element, a precise positioning actuator fixed to the head slider for precisely positioning the at least one head element, and a support for supporting the actuator. The actuator has a pair of movable arms capable of displacing in response to a drive signal applied to the actuator. The head slider is mounted between the pair of movable arms. The head slider and the actuator are adhered by at least one adhesive film.

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 film.
A disk drive apparatus having at least one head gimbal assembly that includes 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 film.
A method of manufacturing a head gimbal assembly with a precise positioning actuator, said method comprising the steps of:
- preparing a head slider with at least one head element, the actuator with a pair of movable arms capable of displacing in response to a drive signal applied to said actuator, for catching said head slider in a space between said pair of movable arms and a support for supporting said actuator;
- adhering top end sections of said pair of movable arms and side surfaces of said head slider by adhesive films, respectively;
- and
- fixing said actuator to said support.
A method of manufacturing a head gimbal assembly with a precise positioning actuator, said method comprising the steps of:
- preparing a head slider with at least one head element, the actuator with a pair of movable arms capable of displacing in response to a drive signal applied to said actuator and a coupling member made of a metal plate member for coupling said pair of movable arms with each other at top end sections of said pair of movable arms, and a support for supporting said actuator;
- adhering an opposite surface of an air bearing surface of said head slider and said coupling member by an adhesive film;
- and
- fixing said actuator to said support.
