| 1. A magnetic write head for perpendicular magnetic recording, the write head comprising:
a return pole;
a shaping layer that is magnetically connected with the return pole;
a write pole that is magnetically connected to the shaping layer;
an electrically conductive coil a portion of which passes between the shaping layer and the return pole; and
a magnetic shield; and wherein:
the shaping layer has a first surface that is coplanar with a first surface of the shield;
the shaping layer is thicker than at least a portion of the shield; and
the shield has a second surface opposite the first surface, and further comprising a layer of alumina covering the second
surface of the shield.
