Abstract: An apparatus includes a substrate and a reader deposited on the substrate. A laser is formed on a non-self supporting structure and bonded to the substrate. A plurality of heat sink layers are deposited between the reader and the laser and configured to provide thermal coupling between the substrate and the laser and sink heat away from the laser. A waveguide is deposited proximate the laser. The waveguide is configured to communicate light from the laser to a near-field transducer that directs energy resulting from plasmonic excitation to a recording medium.
