Abstract:
A light delivery module, a method of fabricating the same, a heat-assisted magnetic recording head using the light delivery module are provided. The light delivery module delivers light emitted from a light source. The light delivery module includes an optical waveguide having an inclined plane of an angle Φ with respect to an incident light axis to deliver an incident light, and a nano aperture changing an energy distribution of the light delivered through the inclined plane to generate an enhanced near-field. The heat-assisted magnetic recording head is mounted on one end of a slider with an air bearing surface to perform a recording operation on a recording medium. The heat-assisted magnetic recording head includes a magnetic path forming unit forming a magnetic field for recording, a light source emitting light for heating a predetermined region of a recording surface of the recording medium, and the light delivery module.
