Sony is working on a new type of blue-violet ultra-fast pulsed laser for optical disks, one that would be used for a new format of super-high-capacity discs. The only problem? We probably won't be using disks anymore when they get around to releasing it.
It's becoming pretty obvious that streaming and downloading are where media consumption are headed.
Sure, streaming doesn't have the quality of Blu-ray, but it will eventually. And with it just being more convenient to not have to deal with physical disks, consumers have decreasing patience to deal with them. But hey, for archiving and professional uses, I'm sure this new format will be a game-changer.
