Researcher's 3-D Digital Storage System could hold a library on 1 disc

Imagine taking the entire collection of historical documents at the Smithsonian National Air and Space Museum and storing it on a single DVD. University of Central Florida Chemistry Professor Kevin D. Belfield and his team have cracked a puzzle that stumped scientists for more than a dozen years. They have developed a new technology that will allow users to record and store massive amounts of data -- the museum's entire collection or as many as 500 movies, for example -- onto a single disc or, perhaps, a small cube.
