Sony Envisions Role of Paper in Optical Data Storage Future

   Sony and Toppan Printing have developed an optical disk that uses the next-generation Blu-ray Disc format and is constructed partially of paper. As much as 51 percent of the optical disk consists of paper, leading to benefits such as reduced manufacturing cost and easy labeling, disposal, and destruction. The ease of destruction (the disks can be cut up with scissors) will help make the disks more secure. Sony and Toppan Printing have been working on the project for a year and are scheduled to present their results at the Optical Data Storage 2004 conference.
   Developed by a 10-company consortium, the Blu-ray Disc format is one of the competing formats for next-generation optical disk storage and can store as much as 27GB of data. Sony recently announced plans to ship a single-side, dual-layer rewriteable disk with a total capacity of 50GB by the end of the year. Sony and Toppan Printing plan to continue development of the paper-based disk to enable volume production in the future.
