Fluorescent Multi-layer Disc
The introduction of the Fluorescent Multi-layer Disc (FMD) smashes the barriers of existing data storage formats. Depending on the application and the market requirements, the first generation of 120mm (CD Sized) FMD ROM discs will hold 20 - 100 GigaBytes of pre -recorded data on 12 - 30 data layers with a total thickness of under 2mm.In comparison, a standard DVD disc holds just 4.7 gigabytes. With C3D's (Constellation 3D) proprietary parallel reading and writing technology, data transfer speeds can exceed 1 gigabit per second, again depending on the application and market need.Increased Disc Capacity DVD data density (4.7 GB) on each layer of data carriers up to 100 layers. Initially, the FMD disc will hold anywhere from 25 - 140 GB of data depending on market need. Eventually a terabyte of data on a single disc will be achievable.
Quick Parallel Access and Retrieval of Information
Reading from several layers at a ime and multiple tracks at a time nearly impossible using the reflective technology of a CD/DVD - is easily achieved in FMD. This will allow for retrieval speeds of up to 1 gigabyte per second.
Media Tolerances
By using incoherent light to read data the FMD/FMC media will have far fewer restrictions in temperature range, vibration and air- cleanness during manufacturing. And will provide a considerably more robust data carrier than existing CD and DVDs.
