As a result, it is possible to manufacture a magnetic detecting element having excellent reproduction output.

Abstract: 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.

Abstract: An anti-reflective film has an anti-reflective structure having many micro holes extending from a reference surface (first surface) in the thickness direction of the film. Each of the holes has an opening exposed at the reference surface, and a bottom facing the second surface on the attachment side. Light incident on the anti-reflective film is mostly introduced into the holes through the openings and diffused by the bottoms, thereby avoiding reflection at a predetermined angle. The ratio of a connecting surface which reflects light is suppressed to increase the ratio of the openings, thereby maximizing the anti-reflective ability of the anti-reflective structure.

Abstract: 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.
