摘要： An information storage medium comprises a substrate, and a magnetic optical recording layer provided on the substrate. A surface portion of the recording layer has a hydrogen-doped portion having a higher hydrogen concentration than that of the other portions of the recording layer. Thus, the recording layer has two portions which have different coercive forces, though being of the same composition. The recording layer is immersed in an aqueous solution having a pH of 4 to 10, to cause hydrogenation reactions to take place on the surface of the recording layer. Another information storage medium comprises a substrate, a magneto-optical recording layer deposited on the substrate, containing a rare earth-transition metal amorphous alloy, and a protective layer deposited on the recording layer. A hydrogenated area is formed by doping hydrogen atoms in the surface portion of the recording layer before the protective layer is formed.
