TDK has recently unveiled a new 10-layer Blu-ray disc capable of 320GB of storage in development.
According to TDK, to quote: "It is possible to write and read data on and from the disc by using a blue-violet semiconductor laser with an oscillation wavelength of 405nm and an objective lens with a numerical aperture (NA) of 0.85, which are currently used for the Blu-ray disc."
This has been a trend in newer, higher-capacity Blu-Ray discs. Due to the proliferation of Internet connections everywhere and firmware being written to non-volatile (update-able) chips, it means that our PlayStation 3 consoles may simply be a firmware update away from reading these 10-layer behemoths of Blu-ray discs.
