Abstract:
1. A perpendicular magnetic recording write head for magnetizing regions in data tracks of a magnetic recording layer comprising: a main pole; a write pole connected to the main pole and having a cross-track width at an end facing the recording layer and a wider cross-track width at a region recessed from the end, the write pole having a throat height from its end to a transition point where its width transitions to its wider width; an electrically conductive helical coil wrapped around the main pole for generating magnetic flux in the main pole and its connected write pole; a flux conductor connected to the main pole, the flux conductor being in contact with the write pole at its transition point and along a portion of its throat height and having a cross-track width greater than the cross-track width of the write pole end; 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; and a return pole.
