OPTICAL RECORDING MEDIUM AND METHOD OF ITS PRODUCTION

摘要

The invention provides an optical recording medium (10) comprising, in order, a substrate (11), a recording layer (12) in the form of a thin film containing Te and N, and optionally Pd, and a protective layer (13) wherein the recording layer (12) in use is imagewise irradiated with a beam of energy to cause a change in the optical properties of the irradiated portions and thereby record information.
