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.
