Researchers at Tohoku University have reportedly figured out a way to “multiply the amount of data that can be stored on a DVD or CD by 9.” Apparently, it works by shaping the pits on a DVD’s surface like Vs, essentially allowing you to get more out of the disc. The problem is that existing DVD & CD players won’t recognize the media made in this way, and for some reason the process can’t be applied to Blu-ray Discs. Still pretty cool though.
