PROBLEM TO BE SOLVED: To inexpensively provide an optical recording medium having a sufficient reflectivity at a film forming time and a high C/N. SOLUTION: The optical recording medium can record and reproduce by irradiation with an energy beam. The medium comprises one recording layer provided on a transparent board. The recording layer mainly contains Sn and at least one type of element selected from the group consisting of group 3B, group 4B, group 5B elements. At least one type of element selected from the group consisting of the group 3B, group 4B and group 5B elements is in a range of 0.5 to 15 atm%. |
