Abstract:
A magnetic claim head comprising:a lower magnetic shield layer, a lower inter-layer insulation film formed on said lower magnetic shield layer, a magnetoresistive effect type element formed on said lower inter-layer insulation film, an upper inter-layer insulation film formed on said magnetoresistive element, an upper magnetic shield layer, made of a material with a resistivity formed on said upper inter-layer insulation film, wherein said lower magnetic shield layer or said upper magnetic film made of a material having a first electric resistivity and a second magnetic film made of a material having a second electric resistivity higher than said first electric resistivity are stacked, wherein said film is provided between (1) all other layers of said lower magnetic shield and (2) said inter-layer insulation film, or (1â€²) between all other layers of said upper magnetic shield and (2â€²) said upper inter-layer insulation film, and wherein said lower magnetic shield or said upper magnetic shield includes an insulating film.
