  Fluorescent Multilayer Disc - Wikipedia, the free encyclopedia
Fluorescent Multilayer Disc (FMD), is an optical disc format developed by Constellation 3D that uses fluorescent, rather than reflective materials to store data.
The main limitation on the number of layers in a FMD is the overall thickness of the disc.
A 50 GB prototype disc was demonstrated at the COMDEX industry show in November 2000.

Fluorescent Multilayer Disc, abbreviated as FMD, is a data storage medium that follows the idea previously used in DVDs, making multiple layers to get more data on one disc, but takes the idea to a new level.
To do this, they have a different fluorescent material in each layer which will reflect a different frequency of light than the other layers making it possible to shine the light through the disc and read the proper frequency for the expected layer.
First generation FMDs were to have roughly 100 GB per disc.

Fluorescent Multilayer Disc, abbreviated as FMD, follows the idea previously used in DVDs, making multiple layers to get more data on one disc but takes the idea to a new level.
Because of this, the main limitation on the number of layers, besides how many different materials can be found to be used, would be to keep the disc from being too thick.
First generation FMDs are to have roughly 100GB per disc and in the future they are expected to be better.

 Optical disc - Wikipedia, the free encyclopedia
In computing, sound reproduction, and video, an optical disc is flat, circular, usually polycarbonate disc whereon data is stored in the form of pits (or bumps) within a flat surface.
This data is generally accessed when a special material on the disc (often aluminum) is illuminated with a laser diode.
The information on an optical disc is stored sequentially on a continuous spiral track from the innermost track to the outermost track.

FMDs, which are under development by C3D (Constellation 3D), are similar to CDs but have a far greater storage capacity.
The fluorescent particles embedded in the grooves and pits of each layer emit radiation when exposed to an external light source, such as a laser.
According to C3D, discs containing up to 100 layers are eventually possible, meaning that one FMD could hold hundreds of gigabytes of data.

Fluorescent Multilayer Disc, abbreviated as FMD, is a data storage medium that follows theidea previously used in DVDs, making multiple layers to get more data on one disc, but takesthe idea to a new level.
Because the normal reflective layers were too limitingmaking it near impossible to get more than two layers on a disc, Constellation 3D decided to find a new way to reflect the lightthat would not interfere with other layers.
To do this, they have a different fluorescent material in each layer which will reflect a different frequency of light than the other layers making it possible to shine the light through the disc and read the proper frequency forthe expected layer.

These extra layers allow FMDs to have capacities up to a terabyte, while maintaining the same physical size of traditional optical disks.
The main limitation on the number of layers in a FMD is the overall thickness of the disk.
After Constellation 3D shutdown due to a scandal and the company consequently running out of money, a new company called D Data Inc. was formed which acquired the entire patent portfolio of Constellation 3D in 2003.

 What effect will FMD have on DVD? - DVD FAQs, DVD Glossary
The various reports of fluorescent multilayer disc (FMD) causing the early death of DVD were wildly exaggerated and not founded in reality.
Fluorescent multilayer technology, which can be used in cards or discs, aims a laser at fluorescent dye, causing it to emit light.
FMD was very cool technology, but it was new, with no track record, developed by one small company.

The capacity of this type of disc is 17 GB, which is twice the capacity of a dual layer disc.
The pits in a recordable disc are generally not indentations of the recording media as seen in the first micrograph of manufactured discs; but instead are optically obscure points that greatly reduce the laser reflectivity.
Even though a disc spins at different RPM to maintain the same read velocity as mentioned earlier, not all discs will spin at the same read velocity when the read head is located in the same position over the disc.

FMD is an acronym which stands for Fluorescent Multilayer Disc.
When the drive's red laser hits the layer, fluorescent light is emitted at a different wavelength than the source light, and that light is read by a sensor that filters out stray light and interference, thereby allowing only light containing data information to be detected.
The FMD fluorescent reflected light is not bothered by passing through layers, or by small defects in the disc.

The design for a FMD ROM model is a 120mm 10-layer disc with 140GB capacity--compared to less than 18GB for a maximum capacity DVD--allowing it to store up to 20 hours of compressed HDTV film viewing.
FMD Microm WORM would be a compact version of the FMD ROM, which enables the user to select the information to be stored.
Second and third generation cards and discs would have capacities up to and exceeding one terabyte.

 Blu-ray Disc - Indopedia, the Indological knowledgebase
Blu-ray Disc is a next-generation optical disc format jointly developed by a group of leading consumer electronics and PC companies called the Blu-ray Disc Association (BDA), which succeeds the Blu-ray Disc Founders (BDF).
The Blu-ray Disc Association is known to be looking into other codecs superior to those supported by the DVD specification.
While future disc technologies may use fluorescent media, Blu-ray Disc systems operate in the same manner as CD and DVD systems and do not make use of fluorescence effects to read out their data.

 New disc format - VMD/FMD (100GB - 1 TB in a few years) - Rev should use it. - Gamespace   (Site not responding. Last check: 2007-10-08)
The VMD (Versatile Multilayer Disc) and FMD (Fluorescent Multilayer Disc) are media storage units which allow data to be stored in multiple layers on a CD (up to 20 right now, and potentially up to 100 within a few years).
I think it's safe to say that a multilayer disc works similarly, but with much more layers, and they can be easily labelled, or not only VMD/FMD game discs, but all multilayer discs in world would look the same.
FMD is the combination of both, since it can also be read by blue laser.

 Wired News:
Fluorescent Multilayer Disc (FMD) is the creation of Constellation 3D and represents a fundamental change in the way optical media is designed.
Compact Disc (CD) and Digital Versatile Disc (DVD) use single and dual metallic layers, respectively, to store data in pits and grooves, similar to the way grooves store music on vinyl records.
Instead of reading a single layer, the data is stored on fluorescent materials in multiple layers, which give off light.

 Geek.com Geek News - Next big thing in data storage
FMD takes the current "pits and lands" coding used on DVDs and then coats the disc with a fluorescent material.
If a disc can be coded to work only once or for a specified amount of time, movie production companies or music studios could come up with a whole new pricing structure and not have to worry too much about people copying discs.
Conclusion, perhaps we will see Sony and/or Toshiba use their R&D departments to come up with a similar format that the FMD disc is based on in 10 years once our 30-50 GB dual-layer discs made with a blue laser have 'soaked' long enough in the market for these companies to make enough profit.
