My first job after college was with BASF. We made 5.25" and 8" "FlexyDisks." How many of us have used 8" disks? I can remember struggling to hand assemble the new 3.5" disks so we could display them at the CES show.
We also developed 3.25" disks with a drive manufacturer, but that obviously didn't work out!
Many of us had uncoated 16" aluminum rigid disks on our walls as mirrors.
