摘要： An optical recording medium of phase change type, and in particular, a dual side medium prepared by adhering two single side media is provided. In this medium, deformation of record marks generated in the overwriting due to difference in light absorption between the record marks and the region other than the record marks is prevented by providing a reflective layer of high light transmission, and increase in jitter and failure of track servo and focus servo caused by uneven coating of the adhesive layer and the resin protective layer are prevented. The optical recording medium comprises a substrate, a recording layer of phase change type on the surface side of the substrate, and a reflective layer and a light absorption layer disposed in this order on the surface side of the recording layer. The light absorption layer has a light transmission of 85% or higher in wavelength range S (wavelength in the range of 400 to 450 nm), up to 55% at the recording/reproducing wavelength, and 80% or higher in wavelength range L (wavelength in the range of 800 to 830 nm).
