Developed by Sony and Toppan Printing, the disc can be read by Sony's new Blu-ray Disc format. It was officially announced on April 15, 2004.
Paper discs are made of 51% paper by weight. They are easy to cut up, making them easily disposable to preserve data security.
Basic structure of a paper disk is similar to the ordinary BD. 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.
