JoshuaInNippon writes: Move over Blu-ray. Japanese researchers from Sony and Tohoku University announced the development of a "blue-violet ultrafast pulsed semiconductor laser," which Sony is aiming to use for disk. The new technology, with "a laser wavelength of 405 nanometers in the blue-violet region" and a power out put "more than a hundred times the world'(TM)s highest output value for conventional blue-violet pulse semiconductor lasers," is believe to be capable of holding more than 20 times the information of current Blu-ray technology, while retaining a practical size. Japanese news reports have speculated that one blue-violet disk could be capable of holding more than 50 high-quality movie titles, easily fitting entire seasons of popular TV shows like 24. When the technology may hit markets was not indicated.
