ABSTRACT:
A disk drive suspension and method has a metal load beam and an electrical interconnect assembly. The interconnect assembly has an insulative layer, a read pair of forward and return path conductive traces, a write pair of forward and return path conductive traces that are supported by the insulative layer, preferably in offset relation across the insulative layer, and a metal layer for grounding and mounted on the insulative plastic layer in fixed spaced relation to the conductive traces to be between the interconnect assembly and the load beam. The metal layer shields the conductive traces from variations in impedance occasioned by varying distances between said electrical interconnect and said load beam.
