ABSTRACT:
A magnetic head includes a first shielding layer, a second shielding layer, an MR element, and a marker layer. The layers and the element are exposed from a medium sliding surface while being inclined at an azimuth angle. A major part of the marker layer is disposed inside two imaginary azimuth lines, which extend straight in one direction through both end portions in the track-width direction of the MR element, in the track-width direction, and both end portions thereof are disposed outside the imaginary azimuth lines in the track-width direction. In the magnetic head, the MR height can be precisely controlled, and changes in asymmetry are reduced.
