DVD and archiving

I know this comes up now and then, but a search yielded no results.

How long will DVDs last? And are the MAM-A gold disks a big improvement for archiving stuff that you want to last for years, e. g. for my little granddaughters?

Perhaps a hundred years if protected properly. Perhaps a hundred seconds if your grandaughter gets her hands on it.

A bigger question is whether the technology to play it will still be around for your grandaughter to use so she can play it 30 years from now.

How many homes still have reel to reel tape machines? -- and I have boxes of tapes that are still (I think) playable.

I think what you say is undoubtedly true. On the other hand, I'm sure that somewhere one could find a CD made from recordings on Edison cylinders - enhanced, even.

The point being, rarely is this stuff totally lost, only transferred (although I understand that some old acetate film stock has crumbled beyond repair.)

My r to r tapes from 1970 are starting to disintegrate.
The coatings are coming off.....
