The magnetoresistive sensor has a bottom shield, a nonmagnetic metallic pedestal, a bottom reader gap, a biasing element, a magnetoresistive stack, current leads, a top reader gap, and a top shield. The nonmagnetic metallic pedestal is positioned on a portion of the bottom shield and the nonmagnetic metallic pedestal has a width less than the width of the bottom shield. The bottom reader gap is positioned on the nonmagnetic metallic pedestal and on the bottom shield such that a portion of the bottom reader gap over the nonmagnetic metallic pedestal is raised relative to portions of the bottom reader gap not over the nonmagnetic metallic pedestal.
