Abstract

The present invention relates to an optical recording medium. 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 Au and a second recording layer containing at least one element selected from the group consisting of Si, Ge, C, Sn and Zn. Therefore, the optical recording medium of the present invention may provide high recording density and transmittance velocity suitable for BD system by combining the recording layer materials.

Description

technical field [0001] The present invention relates to optical recording media. In particular, the present invention relates to a recordable optical recording medium which can densely record data and has high recording stability. Background technique [0002] With the advent of the multimedia era in which video signals including moving images and still images, audio signals, and computer data information are comprehensively processed, packet media including all kinds of optical disks like CDs and DVDs have been widely used. Recently, active efforts have been made to provide optical recording media for recording media such as mobile phones, digital cameras, broadcasting, and movies. [0003] Optical recording media are classified into read only memory (ROM) optical recording media, recordable optical recording media capable of recording information only once, and rewritable optical recording media capable of writing, reading, and repeatedly erasing information. [0004] Th...
