Kodachrome is a black and white film that has color couplers added in the processing. All other modern color film have the couplers integrated. Its the only color film that I know of that was ever considered archival by any measure. every things last longer stored in nitrogen and dark. The thing to do would be to check with the Image Permanence Institute at RIT. https://www.imagepermanenceinstitute.org/

one my disks so the CDs don't matter, last I checked my first Photo CDs
were still readable. I haven't yet had an optical disk that passed
verification fail later, that I've noticed (I do write one-shot disks
that I don't keep or test, so who knows? Those tend to be on the cheap
blanks, whereas I use gold archival for the ones intended for archiving.)
I also hooked up a 5.25" drive to read some old floppy disks 5 years ago
now, and found the disk I really wanted to read (Windows font pack) was
not still readable at least with that drive.
