  • Perpendicular magnetic recording medium having an interlayer of a non-magnetic nickel alloy
    Patent number: 7632580
    Abstract: Perpendicular magnetic recording media and methods of fabricating perpendicular magnetic recording media are described. The perpendicular magnetic recording medium of one embodiment includes an interlayer, an underlayer, and a perpendicular magnetic recording layer. The interlayer is comprised of a Ni-alloy having the characteristics of being nonmagnetic and having an FCC structure. The alloying element for the Ni-alloy may comprise one of V or Cr, or may comprise one of V, Cr, or W. The concentration of the alloying element is set such that the concentration of the alloying element is high enough to make the Ni-alloy non-magnetic, while low enough to maintain an FCC structure for the Ni-alloy.
