OPTICAL DISC, PROCESS FOR PRODUCING THE OPTICAL DISC AND ITS MANUFACTURING APPARATUS

摘要

An optical disc is a disc having a signal recording layer. A treatment film whose surface resistance is 1 x 10<13> - 1 x 10<3> OMEGA is formed on the signal recording layer and electrophotographic printing is applied to the treatment film. The optical disc can be preferably used as a digital audio disc such as a compact disc, a video disc, or an optical disc such as a CD-ROM where digital signals can be recorded, reproduced or erased.
