摘要： A CPP giant magnetoresistive head includes a lower shield layer; an upper shield layer; and a giant magnetoresistive element (GMR) between the lower shield layer and the upper shield layer. The GMR includes a nonmagnetic material layer; a pinned magnetic layer; and a free magnetic layer. The pinned layer and the free layer are laminated with the nonmagnetic layer provided therebetween. A current flows perpendicularly to a film plane of the GMR, the pinned magnetic layer extends in the height direction longer than in a track-width direction and includes a first portion in the GMR. The first portion is disposed above or below the nonmagnetic layer and the free layer. A second portion is behind the nonmagnetic layer and the free layer in the height direction. The first and second portions are in the same plane. The width of the pinned layer in the track-width direction in the first portion is greater than that in the second portion.

摘要： First electrode layers are formed on second antiferromagnetic layers, and in a step separate from the above, second electrode layers are formed above internal end surfaces of the second antiferromagnetic layers and the first electrode layers and parts of the upper surface of the multilayer film with an additional film provided therebetween. Since the first and the second electrode layers are formed separately, it is not necessary to perform mask alignment twice, and hence an overlap structure can be precisely formed in which the thickness of the second electrode layer at the left side is equivalent to that at the right side.
