Title:
REFLECTIVE FILM FOR OPTICAL INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2013/002344
Kind Code:
A1
Abstract:
Provided is an extremely durable reflective film for an optical information recording medium, which naturally has excellent initial characteristics in terms of the jitter value and reflectivity of the optical information recording medium, etc., and which also has no deterioration in these characteristics when stored for a long period of time in a high-temperature, high-humidity environment, even when the thickness of the reflective film is adjusted to be thin in the range of 25 nm or less. The reflective film for an optical information recording medium of the present invention comprises an Al-base alloy including 0.5 to 10% of Si and/or 0.5 to 10% of Ge, and 0.2 to 1.0% of a metal element having a high melting point. The thickness of the reflective film is 25 nm or less.
