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.

You don’t see a watch that features the mug of Leonardo da Vinci everyday. It’s inspired by his backwards writing or “mirror writing”, which some believe to be a code. Others think he was just punking people in the future. The more likely reason is that Leonardo was left handed and preferred to pull a pen as opposed to pushing it across the page in order to prevent the ink from smudging.

And just like the writing in his notebooks, this watch does everything backwards. The numbers on the faceplate are written and listed backwards, and the hour and minute hands move counter-clockwise as well. That should make it a real pain to tell what time it is. The price is $36. That’s not $63 backwards.
