PURPOSE:To obtain an optical information recording medium having an excellent long-term preservable property of information. CONSTITUTION:A recording film 3 is constituted of a multilayered structure contg. >=1 layers of thin films consisting of at least metals, alloys or intermetallic compds. These thin films 3a, 3b are formed by a combination of materials with which the fresh alloys or intermetallic compds. having the higher melting temp. than the melting temp. of the material constituting the respective thin films are formed when these alloys or intermetallic compds. are melted or mixed. The energy of the level lower than the level of the energy applied by an energy beam for recording after information recording is applied to the recording film to melt and mix the respective thin films constituting the recording film, by which the alloys or the intermetallic compds. having the higher m.p. are formed. |
