New Technique For Optical Storage Claims 1 Petabyte On a Single DVD 182
melios writes "Using a two-light-beam method a company claims to have overcome Abbe's Law to dramatically increase the storage density for optical media, to the 9 nm scale. From the article: 'The technique is also cost-effective and portable, as only conventional optical and laser elements are used, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data centre.'"

Another idea: At such high density, who needs a 5.25" disc anyway? A postage stamp would be plenty, and could enable some interesting mobile applications, for just one example.

The "one beam going through a doughnut beam" technique is well known through STED microscopy: http://en.wikipedia.org/wiki/STED_microscopy [wikipedia.org]
STED is a superresolution technique for imaging when using fluorophores.
This is a very nice idea using the technique in a different way for a different application.
