Let's not forget mini disc was a lossy format... not ideal for archival purposes.
Though still reasonably acceptable sound quality for general day to day use.

I got one of mine back out to record our band's gigs 7 or 8 years ago.
I could leave it perched on a shelf down the far end of a pub and not be too bothered if it got nicked.
Which it never did.. any self respecting thief - even drunk - probably turned their noses up at such obsolete equipment....
