TOKYO -- April 21, 2004 -- Toppan Printing and Sony have announced the successful development of a 25 GB paper disc based on Blu-ray Disc technology.

Using the disc structure of Blu-ray Disc technology, the new paper disc has a total weight that is 51 percent paper. The two companies jointly began this optical disc project approximately a year ago. Blu-ray Disc is commonly known for allowing more than two hours of high-definition program recording.

Hideaki Kawai, managing director and head of the Corporate R&D Division for Toppan, said, "Using printing technology on paper allows a high level of artistic label printing on the optical disc. Since a paper disc can be cut by scissors easily, it is simple to preserve data security when disposing of the disc."

Masanobu Yamamoto, senior general manager of the Optical System Development Group of the Optical Disc Development Division at Sony, added, "Since the Blu-ray Disc does not require laser light to travel through the substrate, we were able to develop this paper disc. By increasing the capacity of the disc, we can decrease the amount of raw material used per unit of information."

Toppan and Sony plan to continue the development of the disc for practical use.
