Even though the blank media companies have been touting 200GB Blu-ray discs for years, mostly as part of the psy-ops war against HD-DVD, the largest discs today's players and burners can handle are dual-layer 50GB blanks that burn at up to 8x. A new 450 mw blue laser diode unveiled by Sanyo, however, will enable players to read and burn four-layer 100GB discs at up to 12x speeds. Actual drives with the new laser are still probably a year or two away. [Computerworld]
