Summary: | A magnetic write head having trailing magnetic shield and a trailing magnetic return pole that are recessed from the media facing surface. The magnetic write head includes a write pole, a trailing shield that is separated from the write pole by a non-magnetic trailing gap layer and a trailing magnetic return pole that is connected with the trailing magnetic shield. The trailing magnetic return pole and at least a portion of the trailing magnetic shield have surfaces that face the media facing surface. The surface of the trailing magnetic return pole and at least a portion of the surface of the trailing magnetic shield taper away from the media facing surface. This recess prevents far track interference by preventing stray magnetic fields from the trailing magnetic shield and trailing magnetic return pole from inadvertently affecting the magnetic media. |
