In a 1000 years even if they don’t have the drives, as long as they still know roughly how it works maybe they will photograph it with a microscope and read the tracks in the M-Disc from that. Then they will have to decode it also of course.

Maybe. The question is why are we needing to read these disks in a thousand years. I would guess right now that the most likely case is information we care about is archived on modern formats such as hard drives, which are constantly being copied to different drives as the old ones go out and so in a thousand years they'll still have all the data in a much more accessible format than a very obsolete disk.

If, instead, we are talking about some human disaster and, that constant copies is lost at some point, we're kind of stuck. I don't think the technology to read those disks will exist either, even though in theory, yes, that could be done. It would be a massive reverse engineering effort and I don't think they will even know to start doing that with these weird disks that the agents had.

If you want something archived for a thousand years, well, we know that clay tablets baked worked, although we sometimes can't read the letters but at least seeing something with the eyes says there's something and if there's enough of them we have decoded language.

The best archival paper in ideal conditions lasts more than a thousand years, but in more typical storage, we can't store paper that long. Paper has only been stored successfully in Egypt for that long. I'm sure there are other deserts though that would count just as well.
