Nano DVDs to be the future with 400GB storage and up?

Posted on Wednesday, May 25 2005 @ 00:16 CEST by Thomas De Maesschalck
Iomega filed a patent regarding nano-techlogy based subwavelength optical data storage. The patents is about a technique to encode data on the surface of a DVD by using reflective nano-structures to encode data in a highly multi-level format.

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.
