Paper Abstract

Rewritable DVD (DVD-RAM) 4.7 GBytes products such as DVD-RAM disc, DVD-RAM drive, and DVD Video Recorder have been developed. DVD-RAM can integrate all Audio, Video, Imaging, Computer, and Network applications with write compatibility between DVD-RAM 2.6 GBytes and read compatibility across the entire DVD format family. DVD-RAM disc and drive technologies such as high speed reliable recording, easy operability, secure copy protection functions, and DVD Video Recorder are presented. With the coming of blue light sources, the capacity of the DVD-RAM disc can be upgraded 3 to approximately 5 times, and furthermore could be expanded over 10 times in conjunction with a high-NA optics and a dual-layer disc technology, then 2 to approximately 4 hours high-definition video will be recorded.
