ABSTRACT:
Problem to be solved is that when an information recording medium is repeatedly subjected to recording of information several hundreds times, the atoms in a protective layer are diffused and dissolved into a recording layer to lower a reflectivity greatly and make the medium unendurable to many times of overwriting. This problem can be solved by a medium constituted of interference layer10, interface layer12, phase-change type recording layer14, protective layer13having a tin content of from 23.3 atomic % to 32.3 atomic %, and a heat sink layer8successively formed on substrate1, as seen from a light-incidence side. By use of this medium, the dissolution of atoms can be prevented, and overwriting for many times can be achieved.
