摘要: An optical recording medium (10) comprising a supporting substrate (11), light transmission layer (12), and first dielectric (31), noble metal nitride (23), second (32), absorption (22), third (33), reflective (21) arranged between the (12) (11). The (32) is principally composed of ZnS or mixture SiO2, where ratio to sum SiO2 set be not less than 60 mol% more 100 mol%. material has simultaneously high hardness flexibility in addition thermal conductivity, providing excellent balance conductivity film hardness, this enables small mark formed correct shape.
