I do have discs from that era, as i have 680x0 Mac Performa OS discs - the ones that are silver and black with pixel / icon art of the mac smiley face on them. When i still had an actual SATA optical drive on a machine i was contemplating indexing all of my optical media. I started with some software on windows and it wasn't very good, i looked around for other options and came up with nothing. So i rely on my (admittedly non-perfect) memory of what i had on disc, up to ~30 years ago.

I may as well admit: I tried to "patent" an optical media "case" that mechanically held the middle of the disc, like a laptop cdrom spindle does, but with a button to release them so you didn't need to "bend" the disc to remove it. I had cad drawings and everything. But the vaultz cases are "good enough" for my usage - where i rarely, if ever, remove discs from their sleeves. As long as the cases aren't jostled regularly, and never left open and exposed to dust, and kept in a controlled environment (not too hot, not too cold, not too wet, not too dry), i don't forsee any issues from the storage of the discs. Whether or not the foil layer or glue or any of that holds up - well, my optical disc case design was actually gasket sealed, and had something like a Schraeder valve to pump air out, or nitrogen in; this probably would have made the foil and glue last longer.

I had completely forgotten i had invented that until i started commenting on the longevity of my optical media. Sorry. Amateur archivist, here. Nice to meet you.

It’s so weird, but I can still see an image of the tracker screen from a specific time in my life, and feel echoes of the way it made me feel.
