tl:dr; there is a surface (called ODTS) that you stick the drives to. The surface itself connects to your computer via USB, and its through that the drives' content can be browsed. Not a bad concept. I just fear that the adhesive might not last very long. Unless, if it uses another form of adhesion, such as magnets.
It's both optical, and conducts data via some plastic adhesive. You can't say they haven't thought things through.
