Abstract
A recording medium includes a substrate, a recording layer provided with perpendicular magnetic anisotropy for recording of information, a foundation layer disposed between the substrate and the recording layer, an initial layer which is greater in surface tension than the foundation layer and held in contact with a recoding-layer-side surface of the foundation layer, and a functional layer held in contact with a recoding-layer-side surface of the initial layer.
