Sony and Toppan Printing, a large Japanese printing company, have developed a Blu-ray Disc based on a paper substrate which promises to be more environmentally friendly and secure when destroyed than traditional discs, they say.
Blu-ray Disc uses a blue laser to achieve a storage capacity of around 25GB or around five times that of current DVD discs. It is one of a number of new optical disc storage formats that are being targeted at applications such as storage of high-definition video.

In a Blu-ray Disc the recording layer on which the data is stored lies under a 0.1 millimeter protective layer and on top of a 1.1 millimeter thick substrate. The substrate, or basic surface on which a material adheres, is usually made of a polycarbonate plastic, but the new disc replaces this with paper. The result is a disc of which paper makes up approximately 51 percent of its weight, Sony says.
