| Basic structure of a paper disk is similar to the ordinary Blu-ray Disk. In a BD 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 ] 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. Toppan also had been flirting with the paper disc idea at their San Diego location. Toppan had a local San Diego location, Toppan Electronics at 7770 Miramar rd 92126, their Miramar location featured computer chips and some other confidential projects that never surfaced. They closed their doors at the Miramar location for unknown reasons back in 2004 and to this day the location remains an empty building, but is still owned by Toppan. They tried a new division, Toppan Optical Products in Poway in 2004 and made TV screens for rear projection televisions, but it never caught on. This location has since been sold to General Atomics Corp.<ref>{{cite web|url= http://www.sony.net/SonyInfo/News/Press/200404/04-0415E/ |title= Press release |accessdate= 2008-04-15 |publisher= ] }}</ref> | |||

The paper disc is one of the formats chosen to succeed the DVD. Developed by Sony and Toppan Printing, the disc can be read by Sony's new Blu-ray Disc (BD) format and offers up to 25 GB of storage. It was officially announced on April 15, 2004.
The basic structure of Sony's paper disc is similar to that of a Blu-ray Disc in that 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 substrate. In a Blu-ray Disc, this substrate is made of polycarbonate plastic, which is replaced with paper in a paper disc. This results in a disc containing approximately 51% paper by weight.
Toppan Printing had also been experimenting with paper discs at their San Diego location, which closed in 2004 for unknown reasons. They continued development of the paper disc at a location in Poway, California, but this location also ultimately failed.
