TDK Develops Hard Drive Technology Capable Of 40TB Capacity
Presently, HDD recording density is boosted by the use of a technology called "high magnetic coercivity," but as you could probably guess from the lack of true increases recently, that's about at its limit. TDK's approach involves a heat-assisted recording technology. According to the company, in the new system "the coercivity of the medium, or the amount of reverse magnetic field required to change the value of the stored data, is temporarily reduced by heating it with a laser, which enables writing. As a result, the recording density is further increased."
If all goes well, the tech could be used in a shelf product by 2H 2015, but that sounds a little hopeful to us. We've had our dreams dashed by similar claims before, so we won't be holding our breath on this one. That said, we're still crossing our fingers and toes. Have a look at the video above for a better idea of what's to come.
