Abstract: An apparatus includes a slider body, a laser diode, an optical path, and a heating element. The laser diode is configured to produce energy and is subject to temperature changes as a result of producing energy. The optical path within the slider body is configured to deliver the energy to heat a magnetic recording medium. The heating element is disposed along a length of the optical path within the slider body and is configured to control a temperature of the optical path to mitigate temperature-induced mode hopping of the laser diode.

Abstract: An apparatus comprises a slider of a magnetic recording head having an air bearing surface (ABS), a write pole terminating at or near the ABS, and a near-field transducer (NFT) adjacent the write pole. A light delivery arrangement extends through the slider and terminates at the ABS. The light delivery arrangement is configured to communicate light through the slider and to the NFT. A transparent heat sink layer abuts a terminal end portion of the light delivery arrangement and terminates at the ABS. The heat sink layer has a thermal conductivity greater than that of the light delivery arrangement.

Abstract: A magnetic write head is disclosed that includes a slider that includes a laser diode having a light-emitting edge or surface of a laser diode and an optical waveguide. The disclosed magnetic write head also includes a dielectric layer disposed in a gap between the laser diode and an input to the optical waveguide. The dielectric layer fills the gap completely and provides a low-loss optical pathway for the laser diode to the input of the optical waveguide. Also disclosed is a method that includes spinning on a dielectric in a gap between the light-emitting surface and the optical waveguide coupler, wherein after the spinning on, the laser diode is optically coupled to the optical waveguide coupler through the dielectric.
