Abstract:
A suspension for a disc drive, comprising:a load beam; a flexure coupled to the load beam; an actuator base arranged at a proximal portion of the load beam; at least one piezoelectric ceramic element mounted on the actuator base and adapted to be distorted to displace the load beam when voltage is applied thereto; and an adhesive layer arranged between the at least one piezoelectric ceramic element and the actuator base for fixing the at least one piezoelectric ceramic element to the actuator base, the adhesive layer including an electrical insulating adhesive agent and a plurality of grain fillers of an electrical insulating material mixed in the adhesive agent, the grain fillers having a size such that they are interposed between the at least one piezoelectric ceramic element and the actuator base to secure a clearance for electrical insulation between the at least one piezoelectric ceramic element and the actuator base.
