I love the "theory" that optical media, especially the golden DVDs will be readable in "100 years" or whatever hilariously optimistic length of time claimed. Sure, DVDs and even CDs i have carefully stored in a humidity controlled environment worked the last time i checked, there's always the risk that the next time i pull them out of storage they won't. I think blu-ray is claimed to be even longer than DVD for storage, and i guess it makes sense in theory, the QC/QM needed to pack 120GB on a 12cm disc must be wild. I have books on my bookshelf that are older than 100 years old. I don't think 100 years is even that much to ask, seeing as i know who William Shakesman and Chaucer are. I'm in a unique position, though - my music is on an SD card traveling in space right now, thanks to some attentive friends who petitioned to get me on there. Or so i'm told. How would i know, my spaceship is in the shop.

plastic media optical disks don’t last 100 years, but glass media optical disks do. They exist. My family’s small business used to sell, refurbish, and maintain big jukeboxes for 12 inch Write-Once, Read-Many glass optical disks (in these big minidisc-like cartridges) for customers like big banks that needed guaranteed 50 year archives.

  have you ever read a disk that was 50 years old?

    The tech isn’t yet 50 years old, although accelerated aging is a well-understood field and the margins are good for glass media. However, the tech is 30-40 years old and the early disks ARE still readable.
