MULTILAYER OPTICAL DISC CONSTRUCTION AND FABRICATION

摘要

The present invention is directed to multilayer optical discs that include a plurality of information layers, and at least two different, adjacent separating layers located in a space between at least two of the information layers. Each of the at least two separating layers includes a different polymer that imparts different properties to the disc. Methods of making the discs, and methods of preparing an optical information storage medium, are also included.
