Abstract
A method of manufacturing a magnetic head manufactures a magnetic head having a base, and a laminate stacked on the base and including a magneto-resistive device. The method mechanically polishes a surface of a structure including the base and the laminate close to a magnetic recording medium, wherein the surface of the structure includes an end face of the laminate including an end face of the magneto-resistive device and a surface of the base. Next, the method selectively etches a first region on the surface of the structure close to the magnetic recording medium, wherein the first region includes the surface of the base but does not include the end face of the magneto-resistive device. Subsequently, the method entirely etches the surface of the structure close to the magnetic recording medium.
