High-density blue-laser DVDs that hold 27GB aren't even common yet, and already a group of Japanese companies is looking to the next level: 1TB DVDs. That's 1,000GB, or 218x the capacity of current DVDs that you burn with your computer.
The first generation of Optware's new HVD (Holographic Versatile Disc), however, is expected to hold "just" 100GB or 200GB.
A 1TB disc could hold more than two months of 24-hour TV (just what civilization has been waiting for).
And a Possible Replacement for Flash Memory
Ovonyx has created OUM (Ovonic Universal Memory) that used a material similar to that used by DVD discs to create memory that doesn't forget. Instead of a laser, OUM uses transistors to determine bits.
The company claims that OUM is cheaper to make than flash memory (currently used by almost all digital camera memory cards), packs more densely (more memory inside the plastic package), and can be read-and-written more often than flash memory.
Intel and STMicro are interested. When we read about next year's digital camers taking movies at the same time as high-rez photos, faster memory than flash memory is needed.
