Method for providing a plurality of energy assisted magnetic recording EAMR heads

摘要

A method for providing energy assisted magnetic recording (EAMR) heads using a substrate are 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 method 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 method 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 method also includes separating the substrate into the EAMR heads.
