UCF Researcher develops DVD which holds 1 Terabyte

by Dhiram Shah

Though the war on HD-DVD and Blu-Ray is far from over the battle for the next gen storage solutions is already on with contenders like the Maxell Holographic storage, RVD (Rainbow Versatile Disc) etc. University of Central Florida Chemistry Professor Kevin D. Belfield and his team have developed a new technology which allows users to record and store massive amounts of data on a single disc using their Two-Photon 3-D Optical Data Storage system. Belfield’s team figured out a way to use lasers to compact large amounts of information onto a DVD while maintaining excellent quality. The information is stored permanently without the possibility of damage. The process 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 UCF team has received a $270,000, three-year grant from the National Science Foundation to continue its work.
