发明名称 Two-sided graphical image DVDs and methods for making same
摘要 <p>Methods for forming a single-side-readable DVD (10') having graphical information (70') viewable from the DVD's frontside disc (20') are provided. A first, frontside disc (20') having a first (22a') and a second surface (22b'), with the second surface comprising program information and coated with a semi-reflective coating (24'), is bonded to a second, backside disc (30') having a third and a fourth surface. A first portion of the fourth surface (32b') comprises spillover program information (34') and a second portion of the fourth surface comprises graphical information (38'). The fourth surface is coated with a reflective coating (36'). During DVD formation, the frontside and backside discs are adhesively bonded back to back so that the second surface of the frontside disc faces the fourth surface of the backside disc. Because the frontside disc comprises a semi-reflective coating, the graphical information on the second portion of the fourth surface of the backside disc is viewable through the frontside disc. The graphical information does not affect the playability of the DVD. <IMAGE></p>
