PROBLEM TO BE SOLVED: To prevent the deterioration of an optical recording layer due to an adhesive and to enable an adhesion with high adhesive power by providing the outer peripheral part of the optical recording region between a substrate and the adhesive layer with a tight adhesion intensifying layer and further, providing the region between the adhesive layer and a protective substrate with the tight adhesion intensifying layer as well. SOLUTION: This optical recording medium is constituted by providing the track surface of the substrate 1 for the transparent optical recording medium having performats with an optical recording layer 2 and providing the region between the substrate 1 and the adhesive layer 3 with the tight adhesion intensifying layer 5 on the outer periphery of the optical recording layer 2 and further, providing the region between the adhesive layer 3 and the protective substrate 4 with the tight adhesion intensifying layer 5 as well. The optical recording medium is provided with a hard coating layer 6 on the surface opposite to the surface of the substrate 1 provided with the preformats 7, to protect the outside surface of the substrate. The occurrence of the deterioration of the recording layer by the adhesive is averted by providing the recording medium with such tight adhesion intensifying layers. The adhesiveness between the substrate for the optical recording medium and the adhesive layer or as well as between the protective substrate and the adhesive is thus enhanced. |
