Claim: Fluorescent Multilayer Disc (FMD) is an optical disc format developed by Galaxy 3D that uses fluorescent, rather than reflective materials to store data, however, the use of fluorescence allowed FMDs to operate according to the principles of 3D optical data storage and have up to 100 data layers.
Evidence: Fluorescent Multilayer Disc (FMD) is an optical disc format developed by Constellation 3D that uses fluorescent, rather than reflective materials to store data.
