摘要： At both sides of an element portion, a first hard bias layer having a higher residual magnetization Mr and a second hard bias layer having a higher coercive force Hc are deposited in that order from the bottom with one end of the first hard bias layer being closed close to a free magnetic layer. A film thickness ratio of the first hard bias layer in a whole hard bias layer is from 35% to 75%. This stabilizes magnetization in the free magnetic layer to reduce asymmetry, thus enabling improvement in stability of reproducing characteristics including noise suppression.

摘要： A lower shield layer has a substantially flat shape, and an upper shield layer has a front portion and a rear portion, where the front portion is disposed closer to the lower shield layer than the rear portion. A lower conductive electrode and an upper conductive electrode are disposed between the lower shield layer and the upper shield layer. The lower conductive electrode is electrically connected to the lower shield layer, and the upper conductive electrode is electrically connected to the upper shield layer. Since the lower and upper conductive electrodes are disposed between the upper and lower shield layers, each of the lower shield layer and the upper shield layer may be formed to have a small area and a simple shape.

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.
