Japanese consumer electronics company Pioneer has, according to Nikkei Business Daily, managed to develop an optical disc that holds 500GB of data each side, making it 20 times bigger than the basic single-layer versions of "next generation" optical discs that are based on blue laser (including Blu-Ray and HD-DVD).
The new technology is apparently based on ultraviolet laser, which has shorter wavelength than the blue laser does, thus making it possible to store data much more efficiently on the disc.
