Abstract
A method and system for providing energy assisted magnetic recording (EAMR) heads are described. The heads include sliders and lasers coupled with the sliders. The method and system include molding an enclosure layer. The enclosure layer has a laser-facing surface and a top surface opposing the laser-facing surface. The laser-facing surface has a cavity including a concave section. The method and system further includes providing a reflective layer on the cavity. A portion of the reflective layer resides on the concave section, collimates light from the laser, and provides the collimated light to the EAMR transducer. The method and system further includes aligning the concave section of the cavity with a light emitting portion of the laser. The enclosure layer is also bonded to the slider.
