Any storage is incredibly volatile. Physical players, media, humans struggle with storing, moving things around, finding ways to play it, unless it can be converted to stay with current media mutations.
Consider the rarity of Betamax players, early cellulite film. Obscure media like M-Discs I don't know if there will be players around in 50 years (zip drives anyone?). Or how people won't recognize the media if found in storage.
I feel acid-free paper and ink is still the best for archival. We have 8mm film from my grandparents that are about 60 years old, and my family was able to convert it to digital.
