In this case we are not talking about paper or film, but old analog video and audio tape. This is reel-to-reel audio and quad or u-matic analog video tape. It suffers from even more degradation issues than digital files as you need to maintain the original medium, have no error correction layers, and are faced with an increasing rarity of the specialized equipment needed to read the data. There is also no additional data that advanced techniques will be able to pull from the original low-fidelity source.
