    摘要： Embodiments in accordance with the present invention provide a magnetic head in which broadening of the effective track width can be decreased without reducing the write-field intensity and a variation of the track width can be decreased. A main pole consists of a pole tip having a part which provides the write track-width and a yoke part recessed from the air beating surface in the element height direction, and the pole tip consists of a pole tip at the trailing side where the width in the track-width direction is large and a pole tip at the leading side where the width in the track width direction is small. Moreover, the throat height of the pole tip at the trailing side is made greater than the throat height of the pole tip at the leading side.

    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： In one embodiment, a thin-film magnetic head with a write head has a lower core member made of a soft magnetic film, a planar upper core member made of a soft magnetic film, and a coil conductor positioned between the lower and upper core members. The rear end is equipped with a magnetic body, which at least magnetically joins the lower and upper core members. A magnetic pole piece is in contact with the lower core member and positioned toward an air bearing surface, which faces a recording medium. A first nonmagnetic film is provided between a pedestal magnetic pole piece and upper core member. The write head is structured so that the first nonmagnetic film constitutes a write gap. A second nonmagnetic film is provided above or below the first nonmagnetic film. The edge of the second nonmagnetic film is retracted from the air bearing surface. The upper core member's flare point is positioned toward the air bearing surface rather than the edge of the second nonmagnetic film.
