Hitachi develops new hard drive head technology that will increase storage capacity to 4TB by 2011

Hitachi recently announced that it has achieved a breakthrough in hard drive read-head design.

This breakthrough has produced read-heads in the 30-50 nanometer range, approximately 2,000 times smaller than the width of an average human hair. This new technology is called current perpendicular-to-the-plane giant magnetoresistive heads.

Giant magnetoresistance principles won scientists Albert Fert and Peter Grunberg the 2007 Nobel Prize for Physics.

These new heads will allow Hitachi to expand storage capacity in standard 3.5-inch desktop hard drives to 4TB and extend 2.5-inch laptop hard drives to 1TB of capacity. Hitachi says that it plans to integrate these new heads into hard drives starting in 2009 and that the technology will reach maturity in 2011.

The first products to reach market in 2009 will use recording heads of 50nm and products with recording heads of 30nm will hit market in 2011. Hitachi representatives believe the new heads will allow for storage densities of up to 500GB per square inch. The current highest capacity drives from Hitachi can only pack in 200GB per square inch.

Another benefit of the significantly smaller heads is that the hard drives will product less noise. Test products using 50nm heads produced 40dB of sound while the 30nm heads produced 30dB. Large capacity hard drives that produce less noise will be a welcome addition to digital video recorders.

Hence why you should never browse Daily Tech with so many tabs open at once.

I think he was saying the Nobel Prize winners' tech being used for something, well, useful shows that they deserved the award, whereas Al Gore's "contribution" hasn't really done anything other than gotten the media further amped up about a possibly non-existent problem. (I'm not trying to stir up debate here, just explaining what I think he was getting at.)

I don't think he accidentally wrote the wrong comment for the wrong article. :)

very funny u use the word "possibly"

So u mean we will possibly make life extinct in next 10 years.

What a callous, laid back and brutally irresponsible attitude.
