Imagine taking the entire collection of historical documents at the Smithsonian National Air and Space Museum and storing it on a single DVD.
The above is the start of a very interesting article published at TechNews about a new optical technology developed at University of Central Florida by Chemistry Professor Kevin D. Belfield and his team.
This new technology is named Two-Photon 3-D Optical Data Storage system. 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.
According the article, this technique allows for storing on multiple layers with the capacity of at least 1,000 GB and high quality.
