Nintendo Investigating Holographic Storage
If a recent patent filing is indicative of Nintendo's near-future plans, a truly remarkable solution to the Wii's storage problem could be on the way. The patent, filed in conjunction with Inphase Technologies, is for a holographic storage system that could revolutionize console data storage. Holographic storage works by splitting a laser into two beams - the signal beam, and the reference beam. The signal beam has data encoded onto it by a light modulator, and is then reunited with the reference beam; the combined beams then write the data to a photosensitive material - and the data is stored! The beams read and write at specific light angles, wavelengths, and positions, which essentially make up the data's physical address on the storage medium. Interesting stuff, for sure.
