A HGA comprises a slider and a suspension with a flexure having a tongue region for supporting the slider. A read/write transducer and a piezoelectric element are formed oppositely. The connecting points of the curve beams and the inner tongue of the tongue region are in mirror positions to a center point of the inner tongue, and the connecting points of each curve beam are located at opposite sides of a center axis of the flexure. The slider has multiple electrical pads electrically connecting with the read/write transducer. The inner tongue has multiple electrical pads. The flexure has multiple inner leads electrically connected with the electrical pads of the inner tongue formed on the curve beams. The structure of the HGA prevents the read/write transducer from damaged and cause the manufacture of the HGA simpler. The present invention also discloses a suspension and a disk drive unit.
