Abstract
A system for providing energy assisted magnetic recording (EAMR) heads using a substrate is described. The substrate has front and back sides and apertures therein. The apertures are through-holes between the front and back sides of the substrate. The system includes providing a transmission medium in the apertures and fabricating EAMR transducers on the front side of the substrate. The EAMR transducers correspond to the apertures and the EAMR heads. The system also includes electrically insulating the back side of the substrate. The back side of the substrate is also prepared for mounting of the lasers. The lasers then are coupled the back side of the substrate. The lasers correspond to the EAMR heads and are configured to provide light through the apertures to the EAMR transducers. The system also includes separating the substrate into the EAMR heads.
