Abstract
A recording head has a magnetic write transducer proximate a side of a plasmonic gap waveguide. The magnetic write transducer has a first write pole section that tapers in a crosstrack direction and downtrack direction to form a tapered tip. The first write pole section includes a high-moment, seed layer on one side. A second write pole section is coupled to the first write pole section. The second write pole section extends a second distance away from the media-facing surface less than that of the first write pole section. A tip of the second write pole section is tapered in the crosstrack and downtrack directions.
