Abstract
A method and system for providing an EAMR transducer is described. The EAMR transducer has an ABS and is coupled with a laser. The EAMR transducer includes a write pole, coil(s), and an energy delivery device. The write pole magnetically writes to the media. The coil(s) energize the write pole. The energy delivery device is optically coupled with the laser and includes a top distal from the ABS, a bottom proximate to the ABS, a first side, and a second side opposite to the first side. The first side has a first apex angle from a normal to the ABS and is reflective. The second side has a second apex angle from the normal and is reflective. The first and second apex angles are each at least three and not more than twenty-five degrees. The first and second sides converge such that the top is wider than the bottom.
