Current hard disk drives have hit their limit: a few hundred GB per inch. Or have they? A combination of two unique writing methods could lead to new HDDs that will yield ten times as much data in the same space.
The process combines TAR (thermally-assisted recording) and BPR (bit-patterned recording) to pack bits of data like sardines without the HDD’s write head accidentally messing with surrounding bits. Initially, researchers expect densities of up to 1TB per inch with the new method. Eventually they think they can get densities as high as 10TB per inch.
