| Basic structure of a paper disk is similar to the ordinary BRD. 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. | |||
