Abstract:
1. A perpendicular magnetic recording write head for magnetizing regions in data tracks of a magnetic recording layer comprising: a write pole having an end for facing the recording layer; a main pole connected to the write pole and having an end recessed from the write pole end; an electrically conductive coil wrapped around the main pole for generating magnetic flux in the main pole and its connected write pole; first and second return poles spaced on opposite sides of the write pole in the along-the-track direction; 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; a pair of side shields having ends generally coplanar with the write pole end and spaced on opposite sides from the write pole end in the cross-track direction; and a first layer of nonmagnetic material separating the trailing shield from the side shields.
