PURPOSE:To achieve efficient recording with less radiation energy and to obtain recording medium with long life, by forming a recording layer of an optical rerecording medium with an organic metal compound which is solid at room temperature and absorbs wave length of 3,000-12,000Angstrom . CONSTITUTION:On a base 12 made of glass or the like, an optical conductive thin film 13 and a layer 14 of organic metal compound of II-VIII group which is solid at room temperature and absorbs light of wave length of 3,000-12,000Angstrom , with an method such as a method for coating with the solution of organic metal compound. If required, a protective layer 15 with transparent thin film for the purpose of oxidation prevention of the layer 14 can be provided. Recording is made by forming bits 24 through the rediation of laser light 23 from the layer 14 or changing the color of a layer 13 into black with chemical change or the energy from the bits 24. Thus, a recording medium of a long life can be achieved with less rediation energy. |
