Abstract
A magnetic recording head includes a current perpendicular to the plane read head having a read sensor and a low resistance lead structure. The lead structure includes a layer of conductive material that forms at least a portion of the lead structure such that the layer of conductive material has a lower resistivity than a resistivity of the remainder of the lead structure. The layer of conductive material with lower resistivity decreases the overall resistance of the lead structure.
