Let's be honest - if you gave someone a BlueRay disk *today*, there's a pretty good chance they'd have to go hunting around to find some hardware to read it. 1,000 years from now, you'd have to: - Set up the appropriate laser hardware to scan the physical medium at the appropriate resolution, frequency, etc, while not going so high power that you damage the disc. - Translate the physical pits on the disc to a bitstream. - Translate the bitstream as a filesystem data. - Translate the contents of the files (anyone still have a copy of Word 95?) This technology is probably fantastic on a scale of a few decades, so long as you're careful about which file formats you pick, but if you're serious about centuries or more you'd probably have to stick to something that requires no technology to read, like engravings on glass or non-corrosive metals. (For extra fun, just imagine the fun in a few centuries when amateur archeologists try to figure out these funny markings that turn out to be QR codes https://monuments.com/store/headstones-accessories/living-headstones-qr-code ) On Fri, Jan 27, 2023 at 12:01 PM Tim Keller via WLUG <wlug@lists.wlug.org> wrote:
Here's a question... in a 1000 years.. will you even have a drive that could read such a disk? You'd need to store details manuals with how to construct a drive and the format of the disks.

Last night we were talking about long-term storage media that won't degrade or fail. What you want is M-DISC:

I see you can still buy the media and the drives to _write_ as of recently. Has anyone actually used these?
I did find this interesting site:
And I currently have an external 2Tb USB harddrive in my safe deposit box with family photos and such. I should really buy a new one and do a swap so I have another sitting around.
