Magnetic tape can last multiple decades. There's no telling whether THIS magnetic tape lasted that long, but the medium is pretty hardy.

I recently dug up my father's floppy disks. Stored in a dark dry attic. Each one contained about 10 photos of him on holidays and my birthday when i was 7. I had about 10 usable disks.

The disks are at least 25 years old. He died about 20 years ago.

It is true. Not all photos were saved but the disks held op really well!

I suspect that if you throw resources at the problem, you can tolerate much more degradation than standard tape readers.

No they do not. Where did you get that piece of crap info from?

Magnetic tape storage is pretty standard. depends on many factors but might read just fine.
