A Step Closer to Perfect 3-D Data Storage

July 7, 2010 | Source: Technology Review

The ultimate in holographic (three-dimensional) data storage–a chemically pure crystal composed solely of fluorescent proteins that can be read and reversibly switched between at least two different states using nothing but light from lasers–is being developed in preliminary research by an international group of scientists.

Such a crystal would represent something approaching the theoretical limit of data density in a storage medium: each bit would be represented by a single molecule.
