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.
