Publication number: 20230318257Abstract: 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.Type: ApplicationFiled: March 30, 2022Publication date: October 5, 2023Applicant: Seagate Technology LLCInventors: Fadi El Hallak, Bryn John Howells, Michael Gerald Boyle, Frank Anthony McGinnity, Martin Liam McGarry

Publication number: 20230110250Abstract: 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.Type: ApplicationFiled: December 14, 2022Publication date: April 13, 2023Inventors: Helene Parwana Habibi, Simon Bance, Martin Liam McGarry, Raul Horacio Andruet, Martin Giles Blaber, Weibin Chen, John Charles Duda, Mark Anthony Gubbins, Erik Jon Hutchinson, Vivek Krishnamurthy, Michael Allen Seigler, Chen Wang

Publication number: 20230114979Abstract: 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.Type: ApplicationFiled: October 6, 2022Publication date: April 13, 2023Inventors: Robert D. Turner, Yuhang Cheng, Peter W. Kanas, Martin Liam McGarry, Peter Kevin McGeehin, Kevin R. Heim, Edward Charles Gage, Shaikh Mubassar Ali, Huazhou Lou
