Holographic storage is a technology that we totally don't understand well enough to explain. Apparently, it's a method of storing data in which data is stored throughout the whole volume of a medium, rather than just the surface, allowing for more storage space on a disc. Basically, storage media with multiple-terabyte capacity.
Nintendo's name has shown up as a joint applicant on a patent application by InPhase Technologies for a scanner to read such holographic discs. Is Nintendo planning to solve the hard-drive issue with massive overkill, or are they planning to introduce a new format for their next system's games -- with massive overkill? Maybe nothing will come of this. Or maybe nothing will come of this for a long time.
