Researchers Develop 1TB – 2TB Optical Discs.

Short form: optical disks the size of DVDs are being commercialized that will store 1 to 2 terabytes of data… something like 50 Blu-ray disks worth. This is done by stacking multiple layers (64) of recordable film onto a single disk, rather than making data storage density much higher as was done with CDs-DVDs-Blu-Rays. Even if the disks are expensive, this will be very helpful… I’ve had one 1 tB external drive crash on me taking everything with it, and another go “funny” (but I managed to copy everything over to yet another drive). Having optical disks that are insensitive to being bumped, dust, temperature and humidity will be a great asset.

Prototypes should be ready in about a year, supposedly. No mention of targeted price.
