Patent ID: 8331060

Claim:
A head suspension comprising: a base plate; a load beam; a hinge member through which the load beam is longitudinally attached to the base plate along a longitudinal direction of the base plate; a flexure attached to the load beam to support a magnetic head; an opening formed through the base plate between a base part and a front part of the base plate in the longitudinal direction of the load beam, the hinge member longitudinally protruding into the opening and forming front and rear supports at respective front and rear ends of the opening that extend throughout a bottom portion of the opening; a piezoelectric element disposed in the opening and having front and rear portions thereof respectively attached to the front and rear supports at the respective front and rear ends of the opening by a nonconductive adhesive so that the piezoelectric element minutely moves the magnetic head relative to and in a widthwise direction of the head suspension according to deformation occurring on the piezoelectric element in response to power being applied to the piezoelectric element, the piezoelectric element comprising upper and lower electrodes for applying the power at respective upper and lower surfaces of the piezoelectric element, the lower electrode of the piezoelectric element comprising a peripheral edge disposed inwardly and away from a peripheral edge of the piezoelectric element so as to define a non-electrode portion along the peripheral edge of the lower surface of the piezoelectric element, the lower electrode being connected to a terminal of the flexure, and the peripheral edge of the lower electrode and the non-electrode portion being fixed to the front and rear supports through the nonconductive adhesive at the front and rear portions of the piezoelectric element.
