Laser on slider for a heat assisted magnetic recording head
摘要：
A recording head includes a magnetic write pole having an end positioned adjacent to an air bearing surface, a first waveguide having an end positioned adjacent to the air bearing surface, a laser, and a coupler for coupling light from the laser to the waveguide. The coupler can include a grating positioned in or adjacent to a lasing cavity of the laser.
