MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING/REGENERATING DEVICE

摘要

Provided are a magnetic recording medium, its manufacturing method and a magnetic recording/regenerating device, which are enabled to record/regenerate highly dense information, even if the non-magnetic layers of an intermediate layer to a seed layer are thinned, by keeping the normal orientation of a magnetic recording layer while making compatible the fineness and the high density of the diameters of magnetic crystal particles. The magnetic recording medium is a vertical magnetic recording medium comprising at least a backing layer, an orientation control layer, a magnetic recording layer and a protective layer on a non-magnetic substrate. The orientation control layer is constituted of a plurality of layers of a seed layer and an intermediate layer from the substrate side. The materials for the seed layer and the intermediate layer are selected such that the contact angle of the intermediate layer material to the seed layer material or amorphous is within a range of 10 degrees to 100 degrees.
