1. A magnetic head, comprising:

  • a read transducer and a write transducer at a media-facing surface of the magnetic head;

    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 resulting in a first close point between the media-facing surface and a recording medium, the second energizing current resulting in a second close point between the media-facing surface and the recording medium, the first close point being proximate to the read transducer, the second close point at a different location on the media-facing surface than the first close point; and

    a contact pad disposed at the media-facing surface between the read transducer and the write transducer, wherein the contact pad corresponds to a location near the second close point.
