FMD-ROM

Introduced by Constellation 3D Inc. (C3D), Fluorescent Multi-Layer Disc (FMD-ROM) holds up to 140 GB of data. This is currently 215 times greater than a CD-ROM (.65 GB) and 23 times greater than a DVD-ROM(6 GB).

FMD-ROM discs contain fluorescent materials embedded in the pits and grooves of all 10+ layers. When in contact with a laser, the fluorescent materials are stimulated to produce coherent and incoherent light; data is stored in the incoherent light.

Because the technology isn't based on reflection, multiple layers are read at the same time.

With minor re-tooling, FMD-ROM discs are compatible with existing CD-ROM and DVD-ROM drives. Likewise, FMD-ROM drives are backward compatible, accepting CDs and DVDs.
