PURPOSE:To provide the DRAW type optical recording medium having excellent weatherability. CONSTITUTION:A 1st transparent interference layer 2, an active recording layer 3, a 2nd transparent interference layer 4, and a reflection layer 5 are formed at least in this order on a substrate 1. The 1st and 2nd transparent interference layers 2, 4 are films contg. at least ZnS and SiO2. The active recording layer 3 is a film contg. at least a Ge2Sb2Te5 compd. The reflection layer 5 is a film consisting of an Al alloy and a protective layer 6 essentially consisting of NiCr is formed on the reflection layer 5. |
