Abstract

The present invention is to provide an optical disc which comprises a substrate and a multi-layer structure. The multi-layer structure is formed over the substrate, and at least one layer of the multi-layer structure contains an indicating material. Furthermore, the indicating material has a respective color changeable in response to permeation of oxygen or moisture into the layer containing the indicating material.
