Hmm, so high-density magnetic RAM could be facilitated by nano-sized
rectangular rings:

I guess rectangles are just easier to manufacture using existing
photomask technology. I wonder if it will be possible to have magnetic
processors next?

So will hard drives and DVDs go obsolete? How long will it take to
happen?
