Sony's Blue-Violet Laser the Future Blu-ray?

JoshuaInNippon writes "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 optical disks. 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's highest output value for conventional blue-violet pulse semiconductor lasers,' is believed 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."

According to wikipedia, the light used in a bluray laser is also 405 nm, so that isn't the new part, in case that was confusing for anyone else.
