Optical recording disc and method for recording or reading data on the optical recording disc
Abstract:
An optical recording disc comprises: at least ten optical recording layers; a plurality of intermediate layers each interposed between adjacent optical recording layers; a base film configured to support the optical recording layers and the intermediate layers; a cover layer disposed opposite to the base film with the optical recording layers and the intermediate layers interposed therebetween. The optical recording disc is in the shape of a disc as a whole. The total thickness of the optical recording disc is not more than 300 micrometers, and the optical recording disc provides flexibility.
