25G Paper Disc

Hideaki Kawai, Managing Director, Head of Corporate R&D Division, TOPPAN CO., LTD commented: “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 Optical System Development Gp., Optical Disc Development Div., Sony Corporation said: “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.”

Details will be announced at the SPIE Optical Data Storage 2004 Conference next week.

TOPPAN is also working with E Ink to produce their paper displays.
