Zusammenfassung:	A magnetic write head having a stitched magnetic pole (also referred to as a shaping layer) for conducting magnetic flux to the pole tip portion of a magnetic write pole. The stitched magnetic pole has a shape so as to be thicker in a central region that is aligned with the pole tip of the write pole and is thinner a its outer sides. This shape helps to channel magnetic flux to the pole tip portion of the write pole while maintaining sufficient pole surface area for high data rate recording.
