Abstract:
1. A head gimbal assembly for a head disk drive, comprising: a piezo element mechanically coupled by a flexure to a slider top near a read-write head; wherein said piezo element includes two leads; wherein said piezo element mechanically coupled to said slider is further comprised of: said piezo element bending said flexure to alter a flying height of said read-write head to a rotating disk surface when said leads experience a voltage difference; wherein said read-write head accesses said rotating disk surface; and wherein said peizo element bending said flexure is comprised of at least one member of the collection consisting of: said piezo element bending said flexure to alter a pitch of said slider with said rotating disk surface; and said piezo element bending said flexure to alter a camber of said slider; wherein said flying height of said slider is altered based upon altering at least one member of the collection consisting of: said camber of said slider and said pitch of said slider to said rotating disk surface.
