It's basically a disk like structure, the difference is rather than rotate
the media they move the magnetic domains around. I have a few
128kbyte (1Mbit) bubbles I use still.
Yup, it's sequentially accessed. At least one company still sells &
supports it, though I don't know if they're actually producing it at
this point.. It's a really neat technology. It moves the magnetic
domains around "tracks" in (if memory serves) a crystalline garnet
substrate. These domains can be set to "0" or "1" and are read by
moving them past a detector.
