Toppan and Sony Successfully Develop 25GB Paper Disc

Toppan Printing and Sony today announced the successful development of a 25GB paper disc based on Blu-ray Disc technology. More details will be announced at the Optical Data Storage 2004 conference to be held from April 18th to April 21st at Monterey, California. Using the disc-structure of Blu-ray Disc technology, the new paper disc has a total weight that is 51% paper. "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" says Hideaki Kawai, Managing Director of Toppan Printing. The discs should also be cheaper to manufacture and more ecologically friendly. Toppan and Sony will continue development of the disc for practical use.
