Blu-ray disks are currently limited to a slow 2x write speed, as are the burners. Fortunately, Nichia Corporation looks to change that. Nichia's new laser diode is able to emit pulsed light at 320mW, while it offers a stable operation of 1,000 hours, according to the company. The diode could be used for optical discs including Blu-ray and HD DVD, allowing 10X speed recording with a double-layer disc and 2X speed recording with a four-layer disc. Nichia hopes to make these available by mid 2008. Of course, Blu-ray disks have to be made that can actually support this gigantic boost in burn speeds. TechPowerUp.com
