There's a
seller who's selling the 2.8" Smith-Corona-labeled DataDisk
for about $10 the each new. Drives? Probably cheapest to find a
Smith-Corona PWP with one and scavenge it from there. Bare drives
seem to command an obscene premium as they're used in some old Roland
synths.
Do you know which ones used QuickDisks? The ones I have or have seen
use 3.5 inch disks.

I've got a PWP-5G portable here that uses them, and my notes say that
the PWP-1000, 2000, 90 and 3 used them also. Other than the 5G in my
hot little hands, the list is by no means complete nor authoritative.
A single track recorded as a spiral; the drive positioner works off
of a grooved disc-with-follower driven from the spindle motor through
a clutch. Auto-completes and returns to the beginning of the track
as part of the cycle. Very, very simple. If you wanted to emulate
it in software, it'd be very easy as the datarate isn't particularly
high.
