Are Blu-ray Discs blossoming up in size? That's the latest word on the street! We have heard of BD discs getting theoretical boosts in laboratories, but it's still a 50GB maximum when it comes time to find one in the store. But now, a report from Japan stated that Panasonic is planning to release a 100GB rewritable Blu-ray Disc that's actually compatible with the existing BD-rewritable format that already exists. The trick is that the disc will be a single-sided three-lay disc, rather than dual-layer. Throwing a whole extra layer in definitely enables much more space to be addressed.
