Abstract
A magnetic recording head includes a magnetic recording write element including a main pole having a leading edge and an opposing trailing edge and a first side surface and a second side surface separating the leading edge from the trailing edge. A first side shield gap separates a first side shield from the first side of the main pole and a second side shield gap separates the second side shield from the second side of the main pole. A front magnetic shield is separated from the main pole trailing edge by a front shield gap. A recess extends into the front shield adjacent to the trailing edge, and parallel to the trailing edge. The recess extends laterally away from the main pole and into the front shield a distance greater than the first side shield gap or second side shield gap.
