ABSTRACT:
A reticle having a convex portion and a concave portion is used to form a convex portion and concave portion in the resist pattern for magnetic detection element and conductive layer, respectively. Then, with each resist pattern as a mask, unnecessary portions are removed to determine an initial height and to form a convex portion and concave portion in the magnetic detection element layer and in the conductive layer, respectively. Then, based on a ratio between widths of the convex portion and of the concave portion of the magnetic detection element layer, a deviation of the magnetic detection element layer is obtained, and a deviation of the conductive layer is obtained in a similar way, and based on these deviations the medium facing surface is ground with the conductive layer as a resistance sensor so that the height of the magnetic detection element layer be a desired value.
