That's why 32mb USB sticks were invented.

I think blank CD-Rs were cheaper than any size USB drive at that point...

Absolutely, and the really fancy people even had CD-RW, an opti-magnetic system. But not all disk drives could read them, just like not all computers had an USB port!

Wild times, let's not even get started on DVD-R and DVD+R - we could be here for hours.

CD-RWs are not magneto-optical. MiniDiscs are though.

I knew about MD's, but I thought there was a metal alloy inside the CD-rw's heated up by laser, alligned/written with magnets?

It's a phase change alloy, when writing a high powered laser is used to melt the alloy, when it cools quickly it becomes opaque. When erasing, a lower powered laser heats up the disc and returns it to its transparent state. A reading laser isn't powerful enough to change the phases at all. So, you have the idea right... just no magnets involved.
