Abstract
A magnetic element can be configured with a write pole that continuously extends from an air bearing surface along a plane orthogonal to the air bearing surface. A magnetic shield can be separated from the write pole by a first gap distance on the air bearing surface throughout a tip portion of the write pole and by a second gap distance distal the air bearing surface along the plane orthogonal to the air bearing surface along a body portion of the write pole with the first and second gap distances measured parallel to the air bearing surface and the second gap distance being greater than the first gap distance.
