Abstract
An apparatus comprises a slider of a magnetic recording head, a submount, and an interface defined between the slider and the submount. A laser diode is connected to the submount. A metal layer is provided at the interface between the slider and the submount. The metal layer connects at least about 30% of the surface area of the submount at the interface to the slider and serves as a thermal conduction pathway between the submount and the slider.
