ABSTRACT:
A magnetic head actuator provided with a finely movable tracking device having a piezoelectric element is provided for easy wiring to the piezoelectric element and reducing problems such as wire breakage and continuity defects. In the magnetic head actuator, a portion of an FPC board resin base is removed to expose a portion of the feeding line that extends onto a voltage impressing electrode. An electrical and mechanical connection is made between the electrode and the exposed portion of the feeding line by ultrasonic bonding, Au ball bonding, or stud bumping.
