100x Faster Hard Drive In Lab
Gary lets us know about research out of the Netherlands that has succeeded in reading and writing a hard disk using polarized laser light. The researchers claim this offers a 100-times speedup over reading/writing using magnets. People have been trying for years to write data using polarized light; the secret of the current work's success lies in its disk's materials — gadolinium, iron, and cobalt. Working prototype drives should be available within a decade.

It's been commercially available for years and years and years. 1.6 TB on one disk with 120 MB/sec read speed. Yeah it's write once but still.

the really fascinating thing is not THAT they succeeded to change the magnet field via lasers, it's the speed if you compare their figures to this

Probably not in the notebook/desktop consumer market, but I can imagine enterprise/research uses for magnetic HDDs where read/write times are less important and $/GB much more so.
That said, if I'm right, laser-based magnetic storage being faster than current tech won't really matter for that kind of scenario.
