    摘要： A magnetic writer comprises a write pole and a trailing shield. The write pole is proximate an air bearing surface. The trailing shield is separated from the write pole by a first write gap. The trailing shield is configured with a magnetic layer disposed between the first write gap and a second write gap.

    摘要： A magnetic writer comprises a surface, a write pole, a trailing shield and a gap. The write pole has a write pole tip proximate the surface. The trailing shield is proximate the surface and space away from the write pole. The gap is proximate the surface and located between the write pole tip and the trailing shield. The gap has an effective thickness. The gap comprises a first write gap and a synthesized low magnetization shield. The synthesized low magnetization shield is configured such that a magnetization of the synthesized magnetization shield adjacent the surface has a perpendicular component in an opposite direction to the magnetization of the write pole tip during a write operation.

    摘要： A magnetic recording head includes a magnetic recording write element including a main pole. The main pole has 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 magnetic shield is positioned adjacent the first side surface and a second side magnetic shield positioned adjacent to the second side surface. A first side shield gap separates the first side shield from the first side of the main pole. 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.
