    摘要： A perpendicular magnetic recording medium is formed of a substrate having 5 x 10 5 - 5 x 10 9 fine projections per mm 2 on the surface thereof, said projections having heights in the range of 0.01 - 10 µm and diameters in the range of 0.01 -1 µm, and a ferromagnetic material deposited uniformly in a columnar form on the projections. The recording medium is produced by providing in advance fine projections, the heights and diameters of which are 0.01 - 10 µm and 0.01 - 1 µm respectively, on the surface of a substrate to a density of 5 x 10 5 - 5 x 10 9 projections per mm 2 , and then causing a ferromagnetic material to deposit on the substrate from a vapor phase in such a way that the deposited material is preferentially allowed to adhere onto the projections and then to grow the ferromagnetic material in a direction perpendicular to the plane of the substrate. The present invention has expanded the range of usable substrate-forming materials and recording materials, i.e., ferromagnetic materials, and has also simplified the production process.
