    摘要： Embodiments of the invention provide a magnetic head which prevents data on a recording medium from being erased even when a stray field is applied. In one embodiment, an auxiliary pole is sandwiched between a stray-field shield composed of a magnetic layer recessed from the air bearing surface and a main pole. The stray-field shield may be formed on the leading side of the auxiliary pole. A face of the stray-field shield on a medium side may be recessed from an air-bearing-surface of the magnetic head.

    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.

    摘要： A lower magnetic pole front end portion is provided on a lower magnetic pole main layer, and then, an upper magnetic pole front end portion or an upper magnetic pole front end layer is formed on the flat surface so as to enhance the track width accuracy of thin film head. The height of the lower magnetic pole front end portion is increased so as to enhance the magnetic field intensity. A projection step portion having a width larger than that of the upper magnetic pole front end layer is provided on the lower magnetic pole front end portion. The unnecessary medium in-plane magnetic field can be thus reduced in the off-track position. The respective parts of the head are corrected, thereby realizing a high recording magnetic field intensity exceeding 716 kA/m (9000Oe).

    摘要： A magnetic material having a low coefficient of thermal expansion of 11.5×10−6/K or less is used for forming at least one of a lower shield or an upper shield. A laminated film comprising a layer of the magnetic material having a low coefficient of thermal expansion of 11.5×10−6/K or less, and an 80 wt % NiFe alloy layer, is used for forming at least one of the lower shield and the upper shield. Thus, the thin film magnetic head having reduced after-record noise and reduced thermal protrusion can be obtained.

    摘要： A protrusion 24 having a width Lpfw equal to or somewhat larger than a track width Tw and protruding to the air bearing surface is provided on a lower magnetic pole 5 or lower magnetic pole front end layer 19. The lower magnetic pole 5 or the lower magnetic pole front end layer 19 other than the protrusion is retracted by Lpfd from the air bearing surface 15. With the constitution, since the upper end surface 23 of the lower magnetic pole 5 or the lower magnetic pole to end layer 19 that generates the leakage magnetic fields in the off-track portions is not exposed to the air bearing surface 15, the leakage magnetic fields Hxz in the off-track portions can be decreased greatly.
