摘要:
According to the present invention, there is provided an optical recording medium including at least an information recording layer and a reflective film in which the reflective film is comprised of an AgCu alloy thin film containing Cu the content of which is greater than or equal to 3.0 Äatomic %Ü and less than or equal to 6.5 Äatomic % I. Thus, the optical recording medium can be made inexpensive and weather resistance of "the optical recording medium can be improved, thereby making it possible to avoid characteristics of the optical recording medium from being deteriorated even after it has been stored for a long time.
