Storage start-up fits 250 hours of HD content on one disc

An Israeli start-up has created a way to store a whole lot of data on optical discs using fluorescence.

The TeraDisc looks like a regular CD, except it's chartreuse and see-through. Mempile says its disc will start off able to store 600GB to 700GB and in a year will be able to write 1TB worth of data. There are two physical layers of plastic, but 200 virtual layers on the one-sided disc. That means 250 hours of high-definition content or 300,000 digital photos. HD DVD and Blu-ray Disc can currently hold about 50GB of data on dual-layer discs.
