Patent ID: 7508619

Claim:
A magnetic head which moves over a recording surface of a magnetic disc in a flying manner, rotates about a rotation axis defined outside the magnetic disc, and records data onto the recording surface along tracks formed on the recording surface, the magnetic head comprising: a first write element formed in such a shape that a projection area of a magnetic pole surface which is opposed to the recording surface so as to emit a record magnetic field onto the recording surface does not cross over both track edges of the track included in a first region among the first region and a second region partitioned concentrically on the recording surface in the state where the first write element is positioned on the track included in the first region; and a second write element formed in such a shape that a projection area of a magnetic pole surface which is opposed to the recording surface so as to emit a record magnetic field onto the recording surface does not cross over both track edges of the track included in the second region in the state where the second write element is positioned on the track included in the second region.
