摘要：<p>An information recording medium (1) which includes at least a recording layer (13), and first and second metallic layers (15, 16) disposed on an opposite side of an energy beam incident side of the recording layer and having different compositions, and in which the first one of the first and second metallic layers located closer to the recording layer contains Al, Ag, Au, Pt and Pd as its main components and a sum of contents of these atoms is 60 % or more. Thereby recording and reproducing of information can be realized with a high reliability. <IMAGE></p>
