FLOURESCENT MULTILAYER DISC
[attachment=26473]
WHAT IS FMD?
Fluorescent Multilayer disc is a new technology developed by Constellation 3D Inc.
It stores digital data in three dimensions.
It is a readable and re-writable disc.
It is an optical data storage disc, simialar in size CD-ROMs And DVDs.
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.
FMD RECORDING
Technology Used:- WORM(Write Once Read Many)
Two Rules to be followed while recording.
The write laser should able to turn the fluorescense on or off.
Threshold power of laser for recording and less power for reading.
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
