1TB on a CD? Holographic storage coming soon | Computerworld Blogs:

There's a company named InPhase that apparently is getting ready to bring to the market new optical storage products that will have decent throughput (greater than 20mbytes/sec) and much higher densities than even the latest high density hard drives (515gbits per square inch vs 300 gbits on the latest hard drives).

First drive based on the technology will reportedly have 300GB on a single disk, but soon after will be followed by a family of drives ranging from 800GB to 1.6TB in capacity.

I'm so looking forward to this - for home backups, for work backups, for near-line storage systems at work that don't need 500 disc changers.

It's high time that removable media systems caught up with disk based storage, in terms of capacity.
