Fluorescent storage anyone?

Constellation 3D, Inc. (C3D), New York, NY, is bringing three-dimensional storage a step closer to the masses with the announcement that the company will deliver pre-mass production prototype Fluorescent Multilayer Disc & Card (FMD/C) drives & media for final testing by major drive and media manufacturers in January.

Constellation says that developmental progress on recordable FMD/C drives has ramped up the schedule for mass production of FMD/C-Write Once Read Many (WORM) by several months in anticipation of industrial production next summer.

Pre-industrial production prototypes of recordable FMD/C will now be available to partners in March 2001. These advances will give the companies' production partners time to conduct their own pre-production testing to optimize drive and media quality and speed the standards writing process.

"Public and private demonstrations to potential industry partners of audio, and more recently video Fluorescent Multilayer discs began last fall and have yielded significant business development progress," says President and CEO Dr. Eugene Levich. "Now we are going to be delivering media and drives to existing and potential partners for their own internal testing."

"We are on track to deliver turnkey disc and drive solutions to certain vertical markets by summer 2001, to be followed by broader consumer market introduction shortly thereafter. This is precisely in line with our business plan and shows we are executing our strategy quite well," adds Levich.

Multilayer, fluorescent discs & cards solve signal degradation issues by coating the media with a fluorescent material. When the laser beam hits the layer, fluorescent light is emitted. This emitted light differs in wavelength from the incident laser light and is incoherent in nature, unlike the reflected light in current optical devices. In the read-out system of the drive the light is filtered, detecting only the information-bearing fluorescent light.

Constellation says research has shown that media containing up to a hundred layers of fluorescent storage are currently feasible, making the potential capacity of a single card or disc hundreds of G Bytes or more.

The company's first generation card products, called ClearCard, will be a family of credit card-sized memory storage devices for use in mobile applications. The ClearCards will have capacities up to 5G Bytes.

In the future, cards and discs with capacities exceeding 1T Byte are planned. The company will also be announcing WORM products.
