ABSTRACT:
An information recording medium,15capable of recording information by irradiation of light or applying electrical energy, wherein at least one of first and second dielectric layers102, 106, first interface layer and counter-incident side interface layer103, 105is formed from a Si—In—Zr/Hf—O-based material containing at least Si, In, M1 (M1 represents at least one element selected from among Zr and Hf) and oxygen (O), with Si content being 1 atomic % or more. This medium has high recording sensitivity when information is recorded thereon, high overwrite cycle-ability and high signal intensity.
