An optical recording medium

摘要

An optical recording medium is provided which includes a substrate (10) having pregrooves, and a metal recording layer (20), a buffering layer (30), a reflecting layer (40) and a protecting layer (50), which are sequentially stacked on the substrate, wherein the buffering layer is formed of an organic material having a low light absorption with respect to a laser beam of 600 &tilde& 800nm, such that light absorption (k) is less than or equal to 1.0 at 650nm and the light absorption (k) is less than or equal to 0.1 at 780nm. In this manner, the optical recording medium can be compatible with a compact disc (CD) and have a high reflectivity at longer wavelength than 600nm.
