  • Protective layer for a magnetic recording medium, and a method of manufacturing the same
    Patent number: 10094015
    Abstract: A method for making a magnetic recording medium, including providing a substrate, forming a magnetic layer on the substrate, applying filtered cathodic vacuum arc (FCVA) deposition to form a film on the magnetic layer, and performing nitridation on the film formed by the FCVA deposition.
    Type: Grant
    Filed: July 14, 2014
    Date of Patent: October 9, 2018
    Assignee: FUJI ELECTRIC (MALAYSIA) SDN, BHD.
    Inventors: Wah Lawrence Ng, Se Yong Eh Noum, Mun Sing Fan, Wee Shen Khoo, Naruhisa Nagata
  • GRAPHENE AS A PROTECTIVE OVERCOAT FOR MAGNETIC MEDIA WITHOUT THE USE OF A NUCLEATION LAYER
    Publication number: 20170186457
    Abstract: A graphene layer, used as an anti-corrosive protection medium for magnetic media, overcomes the existing problem of reducing the carbon overcoat layer thickness for magnetic media. Unlike the amorphous carbon that is currently used as an anti-corrosion layer, the impenetrability of graphene to all known gaseous substances enables full corrosion protection of the underlying magnetic medium with a layer of graphene that may be, for example, as thin as a single layer of graphene. The dry transfer of graphene onto magnetic recording disks is enabled, such that the resulting interface of the graphene with the magnetic layer is protested from contact with impurities.
