Abstract

We describe the results of the simulation and the examination and the basic physical characteristics of DVD-RW disc adopting two-depth substrate to deal with read only data on the rewritable material. This feature is required to make the copyright protection and management possible at the same time. Moreover, it will be able to realize the higher compatibility with legacy DVD-players and drives already in the market.
