Akai used a 2.8" spiral disk in a range of

the confusion, the disks were called QD, for "quick disk". The whole
disk was read into memory in one read action, maybe that makes them
quick.

Also used on Smith-Corona portable wapros, called "DataDisk" (as
opposed to "ChoppedLiverDisk") and sold as 2.8". SCM used about
50KHz MFM recording and got about 60K on each.
Same disk as the synth one, different label. I think the drives in
both cases were the same.
