While Sony and others compete with Blu-ray burners of a paltry 8x, Sanyo's looking ahead with a new laser that could enable write speeds of up to 12x. More impressively, the 450 milliwatt diode (twice that of current burners) could read and write through four 25GB layers. If you're not so good at math (it's okay, we had to break out the calculator) that means discs of up to 100GB burned in 10 minutes or less! But don't go running down to your local Blu-ray emporium looking for double-digit speed drives just yet; new standards will be needed for discs that big and drives that fast, which could mean a year or two before production begins. If speculation of Blu-ray's impending demise is to be believed, that may be cutting things a bit close.
