ABSTRACT:
High areal density magnetic recording media exhibiting low noise are formed with a surface oxidized NiAl seed layer. Embodiments include forming the surface oxidized NiAl seed layer on a glass or glass-ceramic substrate, and sequentially depositing a Cr or Cr-alloy, such as CrV, an intermediate CoCrTa layer and a CoCrPtTa magnetic layer.
