PURPOSE:To attain a satisfactory jitter value while attaining a high reflectance by interposing an enhancive layer between a recording layer and a reflecting layer. CONSTITUTION:This optical information medium has a recording layer 2 disposed on the transparent substrate 1, a transparent enhancive layer 6 disposed on the recording layer 2, a reflecting layer 3 disposed on the enhancive layer 6 and reflecting light made incident from the substrate side and a protective layer 4 disposed on the reflecting layer 3. The heat conductivity of the enhancive layer 6 is 0.15-1.5W/mK. |
