Physical media will always be cool IMO, it just makes consuming it a more deliberate activity.
The main thing everyone needs to know is the limitations of a given format in terms of storage and archival:
- Vinyl records should be kept stored out of direct sunlight (I'm looking at those wall display things), and ideally try to keep them around 20 degrees in general. Also avoid cheap and 2nd hand turntables without buying a brand new stylus cartridge. If you can't change the cartridge on a given player, it's trash that will ruin your collection.
- Tapes, either video or cassette should be backed up immediately (unless they're one of the modern resurgence ones), degradation is already happening to the vast majority that were sold back in the day. Some tapes might need to have the little bit of foam replaced which isn't especially hard, but a bit fiddly.
- Commercially manufactured CDs should last at least 50 years or so, but high humidity can apparently diminish this. Anything that might be on a CD-R or similar (think small band merch purchases), get that ripped immediately if you even can. Some CD-Rs have suffered data loss after as little as half a decade.
- DVDs sadly have a potentially lower life than CDs at around 30 years before degradation, but otherwise the rules are the same at CDs
- Blu rays are same again, but shouldn't be much of a worry yet, but it's worth keeping an eye on them as some pessimistic estimates have them only lasting 20 years minimum.
If you're ripping any digital disks and you've got sufficient storage to do so, take the convenience copy (FLACs, an MKV or a CHD) and also a bit-perfect ISO. Discs sometimes have other stuff going on other than the main event and it's good to be able to reproduce the exact original if you ever need to. This is probably only for people who have a home NAS or similar though.
Those are the formats I'm familiar with, I'm not sure what the rules are for minidisk and laserdisk if anyone wants to chime in there
