Hitachi Aims for 10TB Drives With Laser Heat
You know, I have one simple request. And that is to have hard drives with frickin' laser beams attached to their heads!
The future of speedy storage is in solid state, but the capacity advantage will still belong to the magnetic-based parts for the near future.
The one wrinkle in the evolution of hard disk drives is areal density. We may see HDDs grow to 3TB this year, but perpendicular magnetic recording technology is hitting a wall in terms of capacity.
Hitachi may have the solution to that with a method that involves lasers. The addition of lasers tends to improve almost anything, and this is no exception. A 20nm beam of light would be used to heat the storage medium while a magnetic head writes the bits.
The heat-based technology would enable smaller magnetic grains that could pave the way for 2.5 terabit per square inch -- five times the capacity of the densest hard drives of today, according to NordicHardware's explanation. This could mean hard drive sizes of 10TB.

"The addition of lasers tends to improve almost anything"
QFT
i've done some calculation (little bit):
if the HDD space is measured like they do at the moment it means that a 10 TB hdd would have a 'real' storage of 9.09 TB.
I hope that they change this and that you have 10 TB instead of 9 TB ... :S
that's how minidisc works...
THAT, is going to take a very long time to format!
10TB, if I installed every game I had on it I doubt I could filled 2TBs, just imagine trying to backup that to DVDs. THATS OVER 2000 DVDs.
Backups on DVD's is obsolete, the volumes grow too large and a HDD lives longer, you just need a second disc that you only use to back-up.
and if you really want to safeguard your data, put that backup-HDD with family or so (if your house burns down, you lose any backup you have at home...)

That's true for sharks too.
I sure windows 9 and office 2011 will use at least 5 terabytes of that
By the time the technology is in place I doubt the ratio between HDD capacity and SSD will be different from today. It just makes it survive at most.

Good work, unfunny-obvious-man.
Tell me if I'm missing something, please, but what on earth was that first paragraph about?!
