PURPOSE:To obtain a photomagnetic recording medium which is easily formed and is superior in corrosion resistance and recording stability and has high repeatability in writing and erasing, by providing a protective film consisting of a polymer layer on a recording layer on a substrate. CONSTITUTION:A recording layer 2 is provided on a substrate 1, and the protective layer consisting of a polymer layer 3 of PMMA, polystyrene, or the like is formed on the layer 2. Since the protective layer 3 consists of the polymer layer, the photomagnetic recording medium is easy to form and the corrosion resistance is improved, and as the result, the stability is improved, and the repeatability in writing and erasing is enhanced. |
