摘要:
The optical recording medium according to one embodiment of the present invention includes a substrate, a reflective layer located on the upper side of the substrate and reflecting an incident laser beam, and an information recording layer located on the reflective layer. The information recording layer includes a first recording layer containing a compound in the form of AXB1-X (0.8≦X≦0.9), wherein A is Ag and B is Sb and Te, and a second recording layer containing at least one element selected from the group consisting of Si, Sn, Sb and Ge. The laser beam is irradiated on the first recording layer prior to the second recording layer. Therefore, the optical recording medium of the present invention may provide high recording density and transmittance velocity suitable for BLU-RAY DISC system.
