Abstract:
A magnetic head device comprising:a slider having provided thereat a reproducing element and a recording element, with the reproducing element being used to detect a magnetic signal recorded on a recording medium and a recording element being used to record a magnetic signal on the recording medium; a resilient supporting member which supports the slider; and a piezoelectric element, mounted on the resilient supporting member, to change a position of the slider by distorting the resilient supporting member; wherein the piezoelectric element has a piezoelectric layer and a pair of electrode layers which sandwich the piezoelectric layer; wherein the resilient supporting member has a stationary base end portion and a swinging portion, the swinging portion supporting the slider and connected to the stationary base end portion, and the swinging portion being swingable with respect to the stationary base end portion by the piezoelectric element; wherein, with one of the electrode layers of the piezoelectric element opposing the stationary base end portion and the swinging portion, the piezoelectric element is disposed on both the stationary base end portion and the swinging portion; and wherein a surface of the one of the electrode layers, the stationary base end portion, and the swinging portion are joined together through an electrically conductive adhesive resin, and both end portions of the piezoelectric element in directions in which the piezoelectric element expands and contracts, the stationary base end portion, and the swinging portion are joined together through a nonconductive adhesive resin.
