    Abstract: A magnetic head includes a read transducer and a write transducer at a media-facing surface of the magnetic head. The magnetic head includes at least one heater that causes heat deformation at the media-facing surface in response to different first and second energizing currents. The first energizing current results in a first close point between the media-facing surface and a recording medium. The second energizing current results in a second close point between the media-facing surface and the recording medium. The second close point is at a different location in the media-facing surface than the first close point.

    Abstract: An apparatus comprises a write transducer comprising a write pole having a tip portion proximate a media-facing surface and a return pole spaced apart from the write pole in a downtrack direction. The apparatus further includes first and second heat sink portions. The first heat sink portion surrounds a first side of the tip portion that faces the return pole and extends outwards from the tip portion in a cross-track direction. The second heat sink portion comprises a first surface proximate the first heat sink portion and a second surface proximate the return pole and extends outwards in the cross-track direction further than the first heat sink portion.

    Abstract: An apparatus is provided that includes a waveguide adjacent an air bearing surface, a near-field transducer comprising a peg having a side orthogonal to the air bearing surface and a write pole adjacent to the waveguide. The write pole includes a first portion extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface, and a second portion in contact with the first portion comprising a side that extends towards and orthogonally contacts the air bearing surface. The second portion or the write pole defines a gap between the side of the peg orthogonal to the air bearing surface and the side of the second portion of the write pole that extends towards and orthogonally contacts the air bearing surface. A method of making a magnetic recording head that includes the provided apparatus is also disclosed.
