A apparatus includes first and second read transducers arranged on a media-facing surface. The read transducers detect magnetic fields of a recording medium. First and second heaters are disposed proximate the respective first and second read transducers. The first and second heaters independently control respective first and second protrusions of the first and second read transducers from the media-facing surface.
