ABSTRACT:
A method and apparatus for reducing the number of wires needed between the read/write elements and the AE module. An inductive coil and a magneto-resistive element are formed on a substrate such that each includes an input signal lead and a ground return lead terminal. The ground return lead terminal of the inductive coil and the magneto-resistive element share a common ground return lead. The common ground return lead may be formed using a distinct wiring construct or by using a conductive substrate. A conductive suspension may also be formed wherein the conductive substrate is coupled to the conductive suspension. The input signal lead of the inductive coil and the magneto-resistive element may also share a common connector pad for providing signal coupling. A current flow element may be used to control the flow of current through the inductive coil and the magneto-resistive element.
