摘要: A perpendicular magnetic recording medium comprising a substrate, soft underlayer, seed layer, non-magnetic FCC NiW alloy HCP and layer. We have discovered that the combination of layer Ta underlayer uniquely improves media performance thermal stability by achieving excellent coercivity thin bottom narrow C axis orientation distribution.
