AO-DVD (Articulated Optical Digital Versatile Disc) allows 40 to 100 times more storage capacity than current DVDs and allows 5 to 30 times faster data rates, at similar low costs.
Iomega is working to investigate the commercial feasibility of this format and other nano-structural data encoding formats. One possibility being investigated, termed NG-DVD (Nano-Grating - DVD), uses nano-gratings to encode multi-level information via reflectivity, polarization, phase, and reflective orientation multiplexing. Iomega is concurrently evaluating and developing appropriate partners to leverage this intellectual property for producing commercial data storage devices.More details at Physorg
