摘要： A phase change type optical recording medium has a recording layer of a recording material containing elements A, B, and C wherein A is Ag and/or Au, B is Sb and/or Bi, and C is Te and/or Se. Information is recorded by directing a light beam to the recording layer to form recorded marks therein such that the recorded marks are amorphous or microcrystalline while an unrecorded portion of the recording layer remains crystalline, and the A concentration of the unrecorded portion is at least 0.5 atom % higher than the A concentration of the recorded marks. C/N and modulation factor are improved and such improvements are kept even after hot humid storage.
