Abstract
A disk drive head suspension flexure having a gimbal region and a tail includes a metal base layer, an insulation layer over the base layer and two or more pairs of adjacent traces extending over the insulation layer from the gimbal region to the tail. Each trace includes terminals on the gimbal region and tail. Two or more conductive metal signal transmission planes are embedded within the insulation layer and extend from the gimbal region to the tail between the pairs of traces and metal base layer. Each of the embedded signal transmission planes has a width extending across a width of a pair of the traces. Terminals on the gimbal region and tail are coupled to the signal transmission planes by connection vias extending through the insulation layer.
