Abstract
A method and system for providing an energy assisted magnetic recording (EAMR) disk drive are described. The EAMR disk drive includes a slider, at least one EAMR transducer on the slider, and at least one laser coupled with the slider. The slider has a slider back side, a trailing face, and an intersection. The trailing face and the slider back side meet at the intersection. The trailing face makes an angle different from ninety degrees with the slider back side at the intersection. The laser(s) have an optical axis and are optically coupled with the trailing face of the slider. The optical axis is substantially perpendicular to the intersection and parallel to the slider back side.
