Abstract:
1. Apparatus for mechanically mounting and electrically connecting to a piezoelectric element on a head suspension comprising: a. an electrically conductive substrate having a primary plane and forming a part of the head suspension; b. a piezoelectric element having a first major surface that is generally planar and located parallel to the primary plane; and c. an electrically insulating layer between the substrate and the piezoelectric element such that the piezoelectric element is electrically insulated from all metallic structural parts of the head suspension; wherein the first major surface of the piezoelectric element faces toward the substrate and wherein the substrate has an aperture aligned with a portion of the piezoelectric element and the electrically insulating layer has a void aligned with the aperture to provide access for electrical connection to the first major surface of the piezoelectric element through the aperture and void.
