M-DISC: https://en.m.wikipedia.org/wiki/M-DISC

They’re special DVD and Blu-ray discs designed for long-term storage. DVD and Blu-ray are so widely used, it seems likely you’d be able to find some equipment in 30 years that could still read them.

Do you really think physical disc and media players for them will last long? I still cling to an old blu-ray player but every time I buy some discs it feels like I’m sifting through the ruins of a collapsed building (in some giant bin in the middle of a large retailer hallway). I also feel like I never see a single other person looking at or purchasing discs…

Yes.

There are too many use cases for physical and immutable long-term offline storage for this niche to go unfilled, but the niche is too small (at present) to prompt the development of a replacement medium and format, so while I am sure that the materials and read/write hardware will continue to evolve (better data longevity guarantees, read/write speed, physical durability, etc.) the implementations will remain compatible, or at least the reading ones will.

The research suggests that M-DISC Blu-Rays should be fairly durable if not handled often.

I think the disc players are the weak link. I can definitely imagine them going away nigh-entirely in a decade or three.

I didn't manage to find anywhere to buy these in my country. They could be tricky to get.
