Abstract:
A recording head includes a magnetic write transducer proximate a near-field transducer. The magnetic write transduce includes a yoke extending in a direction normal to a media-facing surface and a having an edge facing and recessed from the media-facing surface. A write pole extends beyond the first end of the yoke towards the media-facing surface and overlaps a first surface of the yoke that faces the near-field transducer. The write pole has a stepped edge facing away from the media-facing surface. Two or more coil turns are stacked relative to one another in a down-track direction. The two or more coils face a second surface of the yoke that is opposed to the first surface.
