Magnetic head and magnetic disk storage apparatus mounting the head

摘要

Embodiments in accordance with the present invention provide a magnetic head in which broadening of the write-field distribution in the track-width direction can be decreased without reducing the write-field intensity. A main pole includes a pole tip having a part which provides the write track-width and a yoke part recessed from the air bearing surface in the element height direction, the pole tip including at least two magnetic films having different track-width directions, and the throat height at the trailing side being made smaller than the throat height at the leading side.
