A perpendicular magnetic recording medium includes a hard magnetic recording layer, a soft magnetic layer and a non-magnetic intermediate layer between the hard magnetic recording layer and the soft magnetic layer. The non-magnetic intermediate layer comprises a seedlayer formed adjacent the soft magnetic layer and an underlayer formed between the seedlayer and hard magnetic recording layer. The underlayer comprises Ru or CrRu. The seedlayer comprises CoCrRu, CoCr, W, Ta, Mo, Hf, or Ti. The non-magnetic intermediate layer provides a means for inducing a substantially (00.2) orientation in the hard magnetic recording layer.
