Abstract
A magnetoresistive element is formed by laminating a soft magnetic bias gap layer, a soft magnetic bias layer, a magnetic separation layer, a magnetoresistive layer and a magnetoresistive gap layer, so as to define a sliding surface on which a tape-shaped magnetic recording medium is slid. An upper shield layer and a lower shield layer vertically sandwich the magnetoresistive element therebetween. A vertically stepped portion is provided on each of the upper or the lower shield layer and the respective layers forming the magnetoresistive element, so as to extend horizontally in a track width direction of the sliding surface.
