ABSTRACT:
A method of manufacturing a slider comprises the steps of: forming a slider material including a substrate, a thin-film magnetic head element and an insulating portion; forming a first surface in the slider material by etching a surface of the substrate facing toward a recording medium; forming a medium facing layer in the slider material so as to be adjacent to the first surface; and forming a medium facing surface in the slider material by lapping a surface of the medium facing layer facing toward the recording medium and a surface of the insulating portion facing toward the recording medium. The substrate has a hardness greater than that of the insulating portion. As the substrate and the medium facing layer are compared in hardness, the medium facing layer has a hardness closer to that of the insulating portion.
