    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.

    Abstract: A writer assembly having two separately driven write coils allows a combined write field generated by the writer assembly to be fine turned and optimized for a particular application. Two preamplifiers may be incorporated into a printed circuit board in order to separately drive the write coils. In other implementations, there may be more than two write coils and corresponding preamplifiers.

    Abstract: 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.

    Abstract: A write head having a main pole having a pole tip proximate an air bearing surface (ABS), the main pole having a leading side and a trailing side. The write head also includes a yoke having a yoke tip recessed from the ABS, and a helical coil wrapped around the main pole and the yoke. The helical coil has a first turn with its front edge at least substantially aligned with the yoke tip.
