Patent ID: 8418353

Claim:
A method for providing a plurality of energy assisted magnetic recording (EAMR) heads using a substrate having a front side, a back side, and a plurality of apertures therein, the apertures being through-holes between the front side and the back side, the method comprising: providing a transmission medium in the plurality of apertures; fabricating a plurality of EAMR transducers on the front side of the substrate, the plurality of EAMR transducers corresponding to the plurality of apertures and the plurality of EAMR heads; electrically insulating the back side of the substrate; preparing the back side for a plurality of lasers; coupling the plurality of lasers to the back side, the plurality of lasers corresponding to the plurality of EAMR heads and configured to provide light through the plurality of apertures to the plurality of EAMR transducers; and separating the substrate into the plurality of EAMR heads.
