GE develops 500GB optical disc


The battle for hi-def supremacy might have been won fair and square by Blu-ray, but that hasn’t stopped GE Global Research from busting out a 500GB holographic disc to trounce the format. Of course, you’ll need to bin your shiny new BD player to play the discs, which are the same size as CDs, DVDs and BDs, but store data in three dimensions. And the company reckons the future will see micro-holographic optical discs with capacities exceeding a terabyte. The plan is to offer the discs to archivists in the short term, but GE is not beyond setting its sights on HD-loving consumers in the future.
