  • Oxidation resistant sensor for heat-assisted magnetic recording
    Patent number: 10366720
    Abstract: An apparatus comprises a slider comprising an air bearing surface (ABS) and configured for heat-assisted magnetic recording. The slider includes a writer and a reader at the ABS, a near-field transducer (NFT) proximate the writer, and an optical waveguide optically coupled to a laser source and the NFT. The slider further includes a sensor configured to contact and sense thermal asperities of a magnetic recording medium. The sensor is formed from one of Ru, Rh, Pd, Os, Ir, and Pt.
    Type: Grant

  • Magnetic transducer including basecoat and overcoat
    Patent number: 8582242
    Abstract: A magnetic head that includes: a slider having a leading edge and a trailing edge; and a transducer, the transducer formed on the trailing edge of the slider and the transducer including: a substrate; a basecoat positioned adjacent the substrate, wherein the basecoat includes a material having a Young's modulus that is less than that of alumina and a coefficient of thermal expansion that is less than that of alumina; a reader; a writer; a heater; and an overcoat encasing at least a portion of the transducer, wherein the overcoat includes a material having a Young's modulus that is less than that of alumina and a coefficient of thermal expansion that is less than that of alumina.
