- The Bilkent University Nanotechnology Research Center (NANOTAM) has developed a new technology that enables DVDs to store more than a thousand times as much data as those currently on the market.
Developed by Dr. Ekmel ├-zbay
, the head of NANOTAM, and students ├-zg├╝r Attila ├çakmak and Koray Ayd─▒n, the new nano-materials will pave the way for production of the next era of DVDs, which will be able to store thousands of movies on a single disc.
The invention by the Turkish scientists was published in one of the most prestigious physics journals, the Physical Review Letters. Dr. ├-zbay said they focused their studies on concentrating rays on a point that covers as small a space as possible.
"We have developed a new technology that enhances the number of rays passing through a small dot by thousands of times. With this technology more data will be stored on DVDs in a smaller area," he said.
├-zbay said a normal DVD has a maximum capacity of 50 to 100 gigabytes and that they will increase this by at least a thousand times. "We have created a magical material which enables rays to pass through a very small point," the NANOTAM head noted.
The new technology permits a far smaller notch to be etched on the DVD surface with a wider wavelength. It is expected...
