ABSTRACT:
A laminated perpendicular magnetic recording medium comprises a non-magnetic substrate and at least a pair of polycrystalline, vertically stacked, spaced-apart perpendicular magnetic layers supported thereon, wherein each of the magnetic layers has substantially the same preferred out-of-plane crystal growth orientation and the grains of at least two of the magnetic layers are vertically uncorrelated with each other.
