    摘要： A magnetic write head having a gap structure that improves write head performance. The write head includes a magnetic write pole and a magnetic shield that is separated from the trailing edge of the write pole by a non-magnetic trailing gap layer and is separated from the sides of the write pole by non-magnetic side gap layers. The trailing gap extends laterally beyond the side gap layers, and a convex bump is formed an edge of the magnetic shield at a location near the trailing end of the side gap layers.
