Mini Discs use a different process than burnable cds. I think its more robust, but I can't verify. My 20 (yikes) year old minidiscs all work fine, when I dug them out of storage and tried them.
Tapes can go too. Depending on the binder the tapes have to be baked to restore them. (Video and audio tapes may suffer from this).
When CDs came out people really liked them. They sounded great and didn't involve the care needed with records or tapes (cleaning records and tape pinch rollers... ug). You could skip to any track without flipping it over. Minidiscs came out many years after cds.
Records probably are the most archival since its music in physical form.
