摘要： A combination read/write thin film magnetic head includes an upper-core layer and a lower-core layer sandwiching a gap layer for writing data on a recording medium. The head also includes a magnetoresistive sensor layer for reading data from the recording medium. The magnetoresistive sensor layer is sandwiched by a lower-shielding layer and the lower-core layers, which also serves as an upper shielding layer. Each of the layers is arranged in parallel to one another. The width of the upper-core layer defines the width of a recording track. The width of the gap layer is made equal in length to the width of the upper-core layer to reduce magnetic leakage outside the recording track at the gap layer. The lower-core layer includes a prominence and a lower-core body. The prominence is made narrower to reduce magnetic leakage outside the recording track between the upper-core layer and the prominence. The lower-core body has slanted surfaces extending away from the upper-core layer. The slanted surface reduce magnetic leakage outside the recording track between the upper-core layer and the lower-core body.

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.
