It is clear from the JTEC panel's research and site visits that Japan has pulled ahead of the United States in production of optical storage media and drives. However, at the fundamental R&D level there is still considerable activity going on in the United States: U.S. universities and companies are active and even lead in the more futuristic, high-risk areas. Table 3.1 summarizes the areas of research and development for future optical storage systems and also indicates the areas where there is a significant U.S. presence. Finally, Table 3.2 summarizes the relative status of Japan and the United States in the technologies of optical storage.
