Really -- hardly anything to say on this? Surprisingly few responses,
less than I've received for any other queries. Is there no story here,
media migration just ... works? Nothing to see here, not worth writing
about? Or are some aspects worth addressing?

As devices (DASD, tape, etc.) and media change format or simply age,
how do you ensure you can read what's recorded?
How do you migrate data across changing device types/characteristics?
How much does device topology matter for that? What happens when you
change backup tools/technology? Has your data ever been left behind?
Are backup (likely recent data and relatively transient lifetime) and
archive (long-term or permanent storage) handled differently?
How long do you assume tapes will be readable? Are they stored to
maximize storage integrity? How?
Have you had a data storage problem or catastrophe (earthquake, fire,
smoke, Halon, etc.)? Lost data? Used a recovery service such as
http://www.drivesaversdatarecovery.com/? They have interesting
recovery stories like this:

These issues can be for personal computing or music (e.g., it's tough
reading 5 1/4 floppies or playing eight-track tapes) but I'm more
interested in mainframe experiences for this.
On the boundary between personal and professional areas -- and
speaking of floppy discs and eight-track tapes -- I wonder how many of
us have tape reels, cartridges, or data cell strips that we'll never
be able to read but will never discard. Why is that?
Are there other media issues to cover? (I'll include a paper tape
storage disaster in the story...)
As usual, please copy replies directly to me so they're not buried in
list digests.
Thanks...
