摘要：

We prototyped a next-generation digital-versatile-disc (DVD) dual-layer disc system using a blue laser diode. Numerous technologies were investigated for our proposal, such as new signal-processing techniques, a disc mastering process using photobleachable dye and silver alloy as a semireflective material. The dual-layer disc for the blue laser system has a 27.4 Gbyte capacity on a 12 cm disc. Where the threshold level of the jitter value was provided at 15%, the radial tilt margin was within +/-0.66 degrees on layer 0 and +/-0.64 degrees on layer 1, while the tangential tilt margin was within +/-0.73 degrees on layer 0 and +/-0.70 degrees on layer 1. These values are sufficiently large for the playback system when compared with the DVD system.
