Patent ID: 7167344

Claim:
A magnetic head actuator having a finely movable tracking device comprising: a swing arm extending in a first plane and having a magnetic head at a free end and reciprocally movable around a coarse rotation axis at a base of the swing arm, the swing arm having an opening therein, wherein the opening is defined by edges extending in a second plane substantially perpendicular to the first plane; a piezoelectric element having opposed edges and suspended within the opening of the swing arm, such that the opposed edges are parallel with the edges of the opening; a non-shrinkable adhesive contacting the opposed edges of the piezoelectric element and corresponding edges of the opening, the piezoelectric element having a voltage-impressing electrode for allowing a fine arcuate movement of the free end around the coarse rotation axis in response to an applied voltage; an FPC board having a resin base and a feeding line embedded in the resin base for feeding power to the voltage-impressing electrode, wherein a portion of the resin base is removed to expose a portion of the feeding line that extends onto the electrode; and a direct physical connection between the feeding line and the voltage impressing electrode at the exposed portion of the feeding line.
