ABSTRACT:
A method of manufacturing a magnetic head including a magnetic sensing portion formed of a magnetoresistive effect element, a magnetoresistive effect magnetic head manufacturing method depositing, via a film deposition process, a lamination layer having a free layer comprised of a soft magnetic material of which the magnetization is rotated in response to an external magnetic field, a fixed layer comprised of a ferromagnetic material, an antiferromagnetic layer for fixing the magnetization of said fixed layer, a magnetic flux introducing layer with a tip end of which is opposed to a surface which is brought in contact with or opposed to a magnetic recording medium, and a spacer layer interposed between said free layer and said fixed layer; patterning at least said free layer and said fixed layer with a mask such that opposing side surfaces of said free layer and said fixed layer are formed of one continuous surface; and forming hard magnetic layers having high or low resistance for maintaining a magnetic stability of said free layer in contact with said opposing side surfaces.
