Miti writes: University of Central Florida Chemistry Professor Kevin D. Belfield and his team have developed a new technology that will allow users to record and store massive amounts of data around 1 Terabyte on a single DVD like disc reports Newlaunches. Belfield's Two-Photon 3-D Optical Data Storage system involves shooting two different wavelengths of light onto the recording surface. The use of two lasers creates a very specific image that is sharper than what current techniques can render. Depending on the color (wavelength) of the light, information is written onto a disk. The information is highly compacted, so the disk isn't much thicker. It's like a typical DVD. The challenge scientists faced for years was that light is also used to read the information. The light couldn't distinguish between reading and writing, so it would destroy the recorded information. Belfield's team developed a way to use light tuned to specific colors or wavelengths to allow information that a user wants to keep to stay intact.
