摘要： A magnetoresistive head comprises a free magnetic layer that has first and second free magnetic films sandwiching a non-magnetic intermediate film therebetween, the respective magnetizing directions of the first and the second free magnetic films are antiparallel. The length of the free magnetic layer in the direction of the track width is 200 nm or less, and a difference between a product of saturation magnetic flux density and a film thickness of the first free magnetic film, and that of the second free magnetic film is within a range from 1 to 3 nmT. By this structure, the variation of output and the variation of asymmetry is greatly decreased at a track width of 200 nm or less.

摘要： A recording/reproducing separated type magnetic head comprising a first magnetic domain control layer for arranging the magnetizing direction of a free layer included in a magneto-resistive element to a predetermined direction, and a second magnetic domain control layer for generating a magnetic field in the direction opposite thereto to constitute a differential type bias structure. The recording/reproducing separated type magnetic head decreases an excessively strengthened longitudinal bias magnetic field in a central portion at a narrow track width while avoiding decrease of the fixed magnetic field at the end of the magneto-resistive element in the direction of the track width.
