Abstract
A heat-assisted magnetic recording apparatus may include a slider body, a submount, a laser diode assembly, and a first heat sink. The laser diode assembly comprises a plurality of lateral surfaces and a waveguide-facing surface. The submount is attached to the slider body by a first connector material. A first lateral surface of the laser diode assembly is in contact with the submount, and a second lateral surface of the laser diode assembly is in contact with the first heat sink. The first heat sink is in contact with a second connector material, which is in contact with the slider body to provide a heat flow path from the laser diode assembly to the slider body.
