DVD drive compatible CD recordable media

Abstract

The CD recordable (CD-R) system has been widely accepted in the market, because of its full backward compatibility to the existing CD players and CD-ROM drives. In 1995, the total demand of CD-R media in the world is estimated as 17 million and the rapid increase is predicted in the future. On the other hand, the new high density optical disc system called DVD is proposed and is expected as the promising successor of CD system. To ensure the smooth changing path from the CD to the DVD system, compatibility of CD's to DVD drives is essential.
