If the burner is cheap enough, or you can borrow one, backing up family photos in a way that will be viewable in hundreds of years time would be worth it to me.
I have like 3 pictures I actually care about anymore I'd be more than willing to delete the rest. My parents have always taken like at least a dozen pictures every time we "do something" and I always have to ask... Why drop everything you are doing for a picture that you will, in all likelihood, never look at again. I'd much rather just enjoy the moment tbh
Because in 20 years your memory will be lost. But you'll run across the photo and it will be incredible. It will both remind you and fill in the gaps that your memory lost.
I have all the best photos of my kids printed every year into a photo album. I don't trust digital despite having 3 copies. My 100 year azzo verbatim DVDs kept in black cases in the basement went bad after 10 years. Mdisc on paper should actually last 100 unlike azzo but I don't trust it either.
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.
