Dudes in the Institute of Multidisciplinary Research for Advanced Materials in Tohoku University just developed a 42GB DVD that’s backwards compatible with nothing. The new tech uses a V shape in the pits—current pits are just pits—which allows nine times more information to be held on the same sized disc. The downside is that current CD and DVD drives cant’ read it, so you’ll have to purchase all new tech in order to use this. It’s also not capable of being adapted to Blu-ray drives, so there’s little to no incentive for the industry to add this in to this generation either. But nice work (in theory), Japanese researchers!
