ACTUATOR FOR FINE POSITIONING OF HEAD ELEMENT, HEAD GIMBALS ASSEMBLY EQUIPPED WITH THE ACTUATOR, DISK DEVICE EQUIPPED WITH HEAD GIMBALS ASSEMBLY, AND METHOD FOR MANUFACTURING THE HEAD GIMBALS ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an actuator for fine positioning of head element which causes no increase in thickness of HGA(head gimbals assembly) owing to mounting the actuator, can significantly improve the impact resistance of the HGA, significantly improve the productivity and the quality of the HGA, and to provide a HGA equipped with this actuator, a disk device equipped with this HGA, and a method for manufacturing this HGA. SOLUTION: The actuator which can perform fine positioning of the head element by being fixed to a head slider having at least one head element and to a supporting mechanism, is provided with a pair of arm parts which can be displaced in accordance with a driving signal, and the head slider is fitted between these arm parts.
