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 [atomic %] and less than or equal to 6.5 [atomic %]. 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.

摘要： In a light transmission layer, the elasticity modulus at 25 deg C. is in the range from 1*107 Pa to 5*108 Pa, the elasticity modulus at −20 deg C. is in the range from 4*108 Pa to 5*109 Pa, and the glass transition point temperature is from −20 deg C. to 0 deg C. both inclusive. The Martens hardness of the light transmission layer is 10 N/mm2 or less. The indentation creep of the light transmission layer is 2% or less. The return value of the indentation depth of the light transmission layer is in the range from 0.2 to 2.0 microns. Therefore, both decreasing disc warp and decreasing creep in a light transmission layer can be realized.
