Abstract
A magnetoresistive element for a dual element read head should exhibit uniform current density for proper biasing and Barkhausen noise limiting. Each element is a thin film MR layer normal to the magnetic media. Each element includes a front edge parallel with the magnetic media surface. A back edge, longer than the front edge, is opposite the front edge. Conductors through which current enters and exits the MR layer are adjacent to either end of the back edge.
