摘要： A magneto-optical recording medium comprises a substrate, a magneto-optical recording layer formed of a rare earth metal-transition metal alloy and a dielectric protective layer overlaid in this order on the substrate, and a rare earth metal layer overlaid on an edge face of the magneto-optical recording layer. The magneto-optical recording medium wherein the substrate is annular is made by forming the magneto-optical recording layer, covering the recording region on the magneto-optical recording layer with an annular mask having an outer diameter not larger than the outer diameter of the magneto-optical recording layer and/or an inner diameter not smaller than the inner diameter of the magneto-optical recording layer, overlaying the rare earth metal layer on an outer edge face and/or an inner edge face of the magneto-optical recording layer by dispersing rare earth metal particles toward the annular mask, removing the annular mask, and overlaying the dielectric protective layer on the magneto-optical recording layer.

摘要： An optical disk substrate has a surface on which a pre-groove for light beam tracking is formed. Non-pregrooved regions on the substrate surface on which the pregroove is formed are subjected to surface roughing processing to improve adhesion of the substrate surface in the non-pregrooved regions to a film which is to be overlaid on the optical disk substrate.

摘要： A magnetic recording medium comprises a non-magnetic substrate, a thin ferromagnetic film layer overlaid on the substrate, and a polymer film formed by plasma polymerization. The thin ferromagnetic film layer is composed of ferromagnetic columnar grains. The polymer film is overlaid on the thin ferromagnetic film layer so as to permeate into the spaces between the ferromagnetic columnar grains, thereby improving the corrosion resistance and durability of the magnetic recording medium.

摘要： A process for forming an ultrafine pattern on a surface of a substrate, which includes steps of irradiating the substrate surface with radiation modulated according to information to be patterned, subjecting the substrate surface to deposition with a material reactive or not with the substrate, and subjecting the substrate surface to etching if a substrate-reactive material is used for deposition. By this process, an ultrafine pattern can easily be formed with a high accuracy.
