Abstract
An apparatus includes an apparatus comprising a slider. The slider comprises a substrate comprising a media-facing surface, a first side surface perpendicular to the media-facing surface, and a second side surface opposite the first side surface. A heat sink layer is formed proximate to and thermally coupled to the first side surface of the substrate. A write transducer comprises a waveguide core that at least partially extends from the top surface to the media-facing surface. The waveguide core is formed proximate to and thermally coupled to the heat sink layer. A read transducer is formed proximate to the write transducer such that the read transducer is closer to a trailing edge of the slider than the write transducer.
