MODS

Multiplexed Optical Data Storage or MODS. It is a storage unit which can potentially store up to one terabyte (1,000 gigabytes) of data on one standard-size disc. MODS will be laser-based like DVDs, CDs and the new Blu-ray system but uses much more subtle variations in the way light reflects from the discs. Where existing schemes have patterns of pits that reflect the laser as a series of ones and zeros, MODS can encode and detect more than 300 variations per pit. After error correction and encoding, this leads to 10 times the data density of Blu-ray Disc, currently the record holder for consumer optical storage.
