RegHardware reports that InPhase has managed to record 515 billion bits of information in just one square inch of storage media - a very impressive feat.

The upcoming "Tapestry" drive and madia will apparently have read/write speeds of 23MB/sec and will store 300GB on a disk. InPhase expects to market the system later this year starting with 300GB unformatted capacity, growing to 800GB and eventually 1.6TB as the technology matures.

At 23MB/sec sustained, it will take three hours and 37 minutes to fill a 300GB disk.

InPhase is not without a competitor. Japan's Optware, backed by Toshiba and Intel, is readying a 200GB HVD-RW disk, and is working on a 1TB disk with a 1Gbps (125MB/sec) drive.

Finally, we will have some reasonable media for backing up our ever-larger hard drives!
