Abstract
A transducer suspension system comprises an actuator arm and a suspension. The suspension is comprised of a load beam and a laminated member. The laminated member has an electrically conducting layer and electrical insulating layer, and an electrically conductive support layer. The electrical conducting layer is formed into electrical lines. The support layer is formed into a continuous underlying conductive plane. The conductive plane is connected to the arm by means of a frequency dependent shunt. The combination of the conductive plane and the shunt provide for higher frequency performance with reduced interference susceptibility.
