PERPENDICULAR MAGNETIC RECORDING MEDIUM AND METHOD FOR PRODUCING SAME

摘要

Provided is a perpendicular magnetic recording medium whereby performance is improved such as through lower noise and a better SN ratio, and whereby high-density magnetic recording can be implemented. A perpendicular magnetic recording medium, wherein at least a first non-magnetic interlayer, a second non-magnetic interlayer, and a magnetic recording layer are stacked in the stated order on a non-magnetic substrate, the first non-magnetic interlayer being formed from a Co-Cr-Ru-W alloy and the second non-magnetic interlayer being formed from an Ru-based alloy.
