Nintendo is apparently looking into the growing field of holographic storage to solve the Wii storage issue.

Holographic storage is a new way of storing data in which that data is contained in a 3-D space, as opposed to on the surface of a disk, as is the case in the PS3 or Xbox 360′s HDDs. The technique is pretty cutting edge, but once it becomes mainstream it could be capable of mutli-terabyte storage.

Where Nintendo comes into this story is that its name has appeared alongside holographic storage company InPhase Technologies on a joint patent filing. The filing is for a scanner to read holographic discs.
