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.

Fluorescent Multi-Layer Disc
NEED OF FMD?
• Increased disc Capacity
• Quick parallel access and retrieval information.
• Media tolerances.
• Usage Flexibility.
OPERATING PRINCIPLE
The FMDs are works on the phenomenon of PHOTOCHROMISM.
• The selection of fluorescent material.
• Obtain fluorescent properties.
• Simulation and Emission.
• Filteration and Finish.
Model of FMDs
TECHNOLOGICAL PROCESS OF MANUFACTURE
HOT STAMPING:-
Pressing of sheets.
Formation of layer.
Filling the pits.
Pressing of informational layers.
FMD RECORDING
• Technology Used:- WORM(Write Once Read Many)
• Two Rules to be followed while recording.
1. The write laser should able to turn the fluorescense on or off
2. Threshold power of laser for recording and less power for reading
FMD READ DEVICE
• Reading process is carried out with the help of a photosensitive element.
• Device can read low-power fluorescense of 10 MHz.
• Reading speed upto 1GB/sec.
• Mechanical speed of the derive is 450 times lower than that of DVD.
CD-ROM Vs FMD
COMPRASION OF DISC LAYERS
APPLICATIONS
Data warehouses.
E-commerce related data mining.
Storage of very high detailed archive of maps.
PVR (Priya Village Roadshow), HDTV.
Ability to store a large amount of data in uncompressed format.
ADVANTAGES
Prevents problem of interference since it uses an incoherent fluorescent light.
Compatible with CD and DVD formats with more storage area and faster access.
Fluorescent technology do not require special manufacturing conditions.
Cost of production of FMD is relatively cheap.
It consists multiple data layers, Capacity of each data layer is 4.7 GB
CONCLUSION
Man’s need for additional storage space is increasing .
The FMD Digital Cinema disc has the potential to provide a secure, removable, single disc distribution method.
The FMD can provide us with a staggering 140 GB of storage space seems to be an enticing solution for the storage- hungry masses.
