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.
