An optical recording medium with a number of recording layers that is adaptive for enhancing a light efficiency and for improving a responsibility of information and a recording capacity. In the optical recording medium, at least one of recording layers in the number of recording layers are formed of a material having a non-linear optical characteristic. The recording layer made from the non-linear optical characteristic material has a higher reflective coefficient as a light intensity becomes stronger, thereby improving a light efficiency when a recording layer far away from the light source is accessed. Also, the recording layer made from the non-linear optical characteristic allows an effective diameter of a light spot to be reduced, thereby enlarging a recording capacity of the optical recording medium.
