The quality of the media is in the perception of the user. Ask any audiophile if vinyl is best or not. Analog isn't really the issue here as there would be some kind of multiplexing/demultiplexing encoding or device to interface with it. It would still be discrete and have defined levels. as the technology advances you may be able to define more levels in the same bandwidth space thus creating "more" storage by greater efficiency of the spectrum.
