  • Publication number: 20230318257
    Abstract: A method comprising the steps of forming a recording head comprising a waveguide, a heat sink and a bleed resistor on a first substrate, is described. The bleed resistor is coupled to the heat sink and the substrate. The top surface of the heat sink is planarized to form a planarized heat sink. A laser diode formed on a second substrate is transfer printed onto the planarized heat sink to form an integrated laser diode.

  • Publication number: 20230110250
    Abstract: A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.

  • Publication number: 20230114979
    Abstract: A heat-assisted magnetic recording device is disposed in a hermetically sealed enclosure. The device includes a slider comprising a reader, a writer, and an optical waveguide configured to couple light from a light source to a near-field transducer situated at or near an air bearing surface of the slider. The near-field transducer comprises an enlarged portion and a peg extending from the enlarged portion in a direction of the air bearing surface. A fill gas is provided within the enclosure. The fill gas comprises a mixture of a low-density, inert gas and at least one gas that oxidizes carbon, where the total carbon oxidizing gas concentration of the fill gas is 3-50% by volume. In certain embodiments, the fill gas comprises a hydrogen concentration sufficient to retard oxidation of the peg when the peg is at an operating temperature associated with write operations.
