That's the 2.8M (4M unformatted) Barium Ferrite. I think that it actually
used a "perpendicular (vertical) recording"!
How was the reliability on those?
I used a MicroSolutions Backpack 325 2.8M on a PC for a few years; had a
number of diskettes fail FORMAT.
In contrast, the Floptical (SCSI interface) was reliable, but very slow.
