Patent ID: 7318872

Claim:
A bonding method of a magnetic head micro-motion actuator having a substantially horseshoe-shaped head micro-motion substrate with a pair of movable arms and a magnetic head fixed between the pair of movable arms of the head micro-motion substrate, the method comprising the steps of: measuring clearances between adhesive surfaces of the pair of movable arms and the magnetic head by locating the magnetic head at center of the pair of movable arms of the head micro-motion substrate during bonding the adhesion surfaces of both sides of the magnetic head between the pair of movable arms of the head micro-motion substrate; calculating an optimum amount of an adhesive resin corresponding to the measured clearances; applying the calculated amount of the adhesive resin on the adhesive surfaces of the magnetic head by pulling the magnetic head out of the pair of movable arms of the head micro-motion substrate; and bonding the magnetic head having the adhesive resin applied on the adhesive surfaces between the pair of movable arms of the head micro-motion substrate by inserting the magnetic head therebetween.
