Abstract

See full text

A magnetic element can be constructed by forming a write pole with a tip portion that continuously extends from an air bearing surface (ABS) along a plane orthogonal to the ABS to a body portion that continuously extends from the tip portion distal the ABS. A first write gap layer can then be deposited in contact with the write pole before a processing layer is deposited in contact with the first write gap layer. A magnetic shield may then be formed atop the processing layer with the magnetic shield being separated from the write pole by a first gap distance on the ABS throughout the tip portion and by a second gap distance distal the ABS along the plane orthogonal to the ABS along the body portion. The first and second gap distances can be measured parallel to the ABS with the second gap distance being greater than the first gap distance.
