What exactly happened to the DVDs in the basement? That's really interesting, indeed DVDs also claimed 100+ years of life span, but as you can see that's only the theoretical maximal in perfect conditions, which don't exist in real life, and the same thing happened to your DVDs can happen to Blu-Ray disks too
M-Discs are not like standard Blu-rays, they were designed specifically for long-term archive storage. If you follow the link at the top of this thread you can get some more detailed information on them. They're supposed to last several hundred years, but of course no one has empirical evidence of that yet.
Ooo I see! That's awesome!
Yeah unfortunately we don't have hundred-years data on them lmao but at least it would still be interesting to see how examples of such disk go as years and decades go by :p
Burned DVDs use a dye that turns dark when hit with a laser. The dye was claimed to be stable for 100 years but wasn't. Mdisc is different and should last longer.
