Abstract:
1. A magnetic write head, comprising: a substrate having a surface; a magnetic yoke formed as a single, integral layer along a plane that is substantially parallel with the substrate surface; and a magnetic write pole connected with the magnetic yoke, the magnetic write pole being configured for perpendicular magnetic recording and having an end that extends to an air bearing surface and having a trailing edge and a leading edge, the trailing edge being wider than the leading edge as viewed from the air bearing surface; wherein a portion of the magnetic yoke passes over the trailing edge to provide a trailing magnetic shield and being separated from the trailing edge of the write pole by a non-magnetic trailing gap layer; and wherein the magnetic yoke further comprises first and second laterally opposed magnetic return poles each having an end extending to the air bearing surface and a flux guide portion disposed between the first and second return poles, the flux guide portion terminating short of the air bearing surface and being magnetically connected with the magnetic write pole.
