A magnetic recording medium includes a substrate, a base layer, a first magnetic layer, and a second magnetic layer, stacked in the order named. In this recording medium: the first magnetic layer contains magnetic particles having an L1structure; the second magnetic layer has a granular structure, in which magnetic particles having the L1structure, and grain boundaries including hexagonal boron nitride, are contained; (111) surfaces of the magnetic particles contained in the first magnetic layer are coated with aluminum nitride at an interface with the second magnetic layer; the magnetic particles contained in the second magnetic layer grow epitaxially from (001) surfaces of the magnetic particles contained in the first magnetic layer; and the magnetic particles contained in the first magnetic layer and the magnetic particles contained in the second magnetic layer form columnar crystals that penetrate, respectively, the first magnetic layer and the second magnetic layer.
