Abstract:
1. A head gimbal assembly comprising: a slider having a substrate with a trailing edge, a leading edge opposite the trailing edge and an air bearing surface connecting the trailing edge with the leading edge, a read/write transducer formed at the trailing edge, and a piezoelectric element formed at the leading edge; and a suspension with a flexure having a tongue region for supporting the slider, the tongue region having an outer tongue, an inner tongue formed within the outer tongue and a pair of curve beams connecting the inner tongue with the outer tongue, the connecting points of the curve beams and the inner tongue being in mirror positions to a center point of the inner tongue, and the connecting points of each curve beam located at opposite sides of a center axis of the flexure along a longitudinal direction thereof; wherein the slider has a plurality of electrical pads electrically connecting with the read/write transducer formed on a surface opposite to the air bearing surface thereof, the inner tongue has a plurality of electrical pads corresponding to the electrical pads of the slider formed thereon, and the flexure further has a plurality of inner leads electrically connected with the electrical pads of the inner tongue formed on the curve beams.
