摘要:
A method and system for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser. The EAMR transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The EAMR transducer includes a write pole, at least one coil, a waveguide and an output device. The write pole is configured to write to a region of the media. The at least one coil is for energizing the write pole. The waveguide has an input optically coupled to the laser and configured to direct energy from the laser toward the ABS for heating the region of the media. The output device is optically coupled to the waveguide. The output device coupling out a portion of the energy not coupled to the media.
