What about M-DISC DVDs and BluRays? Archival grade,
not susceptible
to magnetism or EMP. I think BluRay discs are made of a harder material than DVDs
and don’t scratch as easily.

I care, and would like to know more.
Even without nuclear bombs, which I stopped worrying about 60 years ago, I
have occasionally had to deal with damaged data, from causes much more
mundane than EMPs.
I have had magnetic, AND optical media that have "gone bad".
I am interested in whatever media are more likely to still be readable in
a few decades.
M-Disc claims 100 year life, but, obviously, no M-Disc has lasted that
long, and they are making promises based on what they THINK will happen.
M-Disc BDXL is currently available in 100GB per platter.
