ABSTRACT:
In order to provide a laminated optical disc having a sufficient display portion and a reliable print display, a pair of disc substrates are bonded together to form an optical disc, in which one disc substrate is colored and contents of recorded matters are displayed on the surface thereof so as to eliminate the ground solid print layer for the print display layer and to avoid deformation or warping of the disc.
