Patent ID: 7207100

Claim:
A method of manufacturing a magnetic head having a base, and a laminate stacked on said base and including a magneto-resistive device, said method comprising: a polishing step for mechanically polishing a surface of a structure including said base and said laminate close to a magnetic recording medium, said surface of said structure including an end face of said laminate including an end face of said magneto-resistive device and a surface of said base; a first etching step after said polishing step for selectively etching a first region on the surface of said structure close to the magnetic recording medium, said first region including the surface of said base but not including the end face of said magneto-resistive device; a second etching step after said polishing step and before or after said first etching step for entirely etching the surface of said structure close to the magnetic recording medium; and a step of setting a target region for said first region, said target region including a region on the surface of said base on the surface of said structure close to the magnetic recording medium, and a predetermined region close to said base in a region on the end face of said laminate on the surface of said structure close to the magnetic recording medium, wherein said predetermined region in said target region set for said first region has a width in a range of 0.05 μm to 3.0 μm.
