Have you filled up your external hard drives and even Blu-ray’s 25GB seems insufficient for storage?
Pioneer, a Japanese electronics maker has been working on an optical disc which can store 25GB per layer. So what’s the difference you ask? Their discs consist of 16 layers of storage for a total of 400GB on a single disc as opposed to the max of 50GB for a dual layer Blu-ray disc. Pioneer says that the lens specification for reading their discs could be close enough to blue-ray for them to maintain compatibility but they make no promises as yet. They plan to demonstrate the tech at an industry conference next week. For now it seems the disc is read only but they will obviously add write capability to it before its commercial release.
