Interesting question...
I don't know if it's doable, here's a possible start for your research: http://www.digital-detective.co.uk/documents/Volume%20Serial%20Numbers.pdf

Thank you for your hint, it's very interesting, and it helped me a little step. I will go on looking for some more details. I also posted this question in some other forums, if there is an answer, I will post this answer here, too. cu

Here's more to read: http://computermuseum.informatik.uni-stuttgart.de/dev/ibm_5110/technik/en/diskops.html
It's a diskette volume label description for an ancient IBM 5100 computer and according to that volume label structure it can be prove that two diskettes were written on a same computer or not. Unfortunately I cannot find this kind of description for current diskette formats. Hope you'll have more luck.
