  • PERPENDICULAR MAGNETIC RECORDING MEDIUM WITH IMPROVED MAGNETIC ANISOTROPY FIELD
    Publication number: 20100035085
    Abstract: A perpendicular magnetic recording medium comprising a substrate, a soft underlayer, a seed layer, a non-magnetic FCC NiW alloy underlayer, a non-magnetic HCP underlayer, and a magnetic layer. We have discovered that the combination of a seed layer comprising Ta and a NiW alloy underlayer uniquely improves media recording performance and thermal stability by achieving excellent coercivity of the thin bottom magnetic recording layer and narrow C axis orientation distribution.
