Sony Corp. has announced the development of a 25GB disc that is 51% paper. The disc, based on Blu-ray disc technology, was developed in conjunction with Toppan Printing Co. of Tokyo.

The Blu-ray standard is a potential next-generation DVD format, jointly developed by 13 consumer electronics and PC companies. The format was developed to enable recording, rewriting and playback of high-definition television (HDTV). Blu-ray allows over two hours of HDTV or more than 13 hours of standard-definition television on a 27GB disc.

Sony, which plans to introduce Blu-ray disc players in the U.S. in 2005, discussed details of the paper disc at the Optical Data Storage 2004 conference, held April 18-21 in Monterey, Calif. According to the International Society for Optical Engineering, one of three organizations that manages the Optical Data Storage conferences, the paper disc generated strong interest among attendees.
