| Abstract(in English) | To realize the next generation DVD having a 13～15 Gbyte recording capacity, we studied mastering processes to extend a resolution limit of the Laser Beam Recorder(LBR) and devised a new mastering process. It uses photobleachable dye which is coated over the photoresist layer. Approximately 20% improvement resulted in a line recording density resolution in the case where the photobleachable dye, having large A parameter and small B parameter is used together with a Photoresist, whose sensitivity was adjusted to that of the photobleachable dye. By this process, a glass master was made having a 0.175μm pit-length and a 0.4μm track-pitch. These figures show that this new technology can be applied to make a 15 Gbyte glass master still leaving some margin. |
