- The patent covers a novel technique of encoding data on the surface of a DVD by using reflective nano-structures to encode data in a highly multi-level format. This technology, termed AO-DVD (Articulated Optical - Digital Versatile Disc), allows more data to be stored on a DVD and could allow future optical discs to potentially hold 40-100 times more information with data transfer rates 5-30 times faster than today's DVDs, and at similarly low costs.
