Patent ID: 7768744

Claim:
A perpendicular magnetic recording write head for magnetizing regions in data tracks of a magnetic recording layer comprising: a main pole; first and second return poles spaced on opposite sides of the main pole in the cross-track direction, the main pole and return poles lying in the same plane; a write pole connected to the main pole and having an end facing the recording layer; an electrically conductive helical coil for generating magnetic flux in the main pole and its connected write pole, the helical coil comprising a main pole portion wrapped around the main pole in a first direction, a first return pole portion wrapped around the first return pole in a direction opposite said first direction, and a second return pole portion wrapped around the second return pole in a direction opposite said first direction; and a trailing shield having an end generally coplanar with the write pole end and spaced from the write pole end in the along-the-track direction.
