Eschewing the reflectivity principles in current optical media entirely, the TeraDisc system uses light-sensitive molecules called chromophores to create hologram-like matrices that can be used to store a full terabyte of data on a single disc using a red laser -- and Mempile says that an eventual transition to a blue laser system will enable storage capacities of up to 5TB. The company is hoping to get a prototype ready in 18 months, and plans to ship the first version a year after that, priced around $3,000 for the drive and $30-60 for a 600GB disc. No word on the price of those 1TB discs, but you can bet they won't be cheap." Thats crazy!
