Abstract: A magnetic shield may be capable of enhancing magnetic writing, particularly in transducing elements accessing data bits from data tracks. At least one magnetic shield is adjacent a write pole. The shield has a flux concentration feature on an air bearing surface (ABS) capable of enhancing magnetic undershoot between the shield and the write pole.

Abstract: A write head, the write head having an air bearing surface, the write head including a magnetic write pole, wherein at the air bearing surface, the write pole has a trailing surface, a leading surface that is opposite the trailing surface, and first and second surfaces; a trailing shield proximate the trailing surface of the magnetic write pole; first and second gaps proximate the first and second surfaces of the magnetic write pole; first and second side shields proximate the first and second gaps, each of the first and second side shields having a trailing shield surface; and first and second antiferromagnetic-coupling layers positioned between the trailing shield surfaces of the first and second side shields and the trailing shield.
