To cram more data on DVDs than the high-density Blu-ray format allows, manufacturers will have to go three-dimensional and stack data in multiple layers. Researchers at the Swinburne University of Technology, in Hawthorn, Australia, have now found a way to add two more dimensions to optical-disc recording: wavelength and polarization. The technique could pack 1.6 terabytes of data on a standard-size DVD, the researchers say—the equivalent of 30 Blu-ray discs. (source: spectrum.ieee.org)
