Abstract:
A magnetic write head having write pole and a wrap-around-trailing magnetic shield having side portions that are separated from the write pole by tapered non-magnetic side gap layers. The tapered non-magnetic side gap layers provide a non-magnetic side gap width that increases with increasing distance from the ABS, thereby providing optimal protection against adjacent track interference at the ABS while minimizing write field loss to the shield in regions away from the ABS.
