You read it right. I think only Zenith and Fujifilm made them.

Years ago I bought a portable with 2.5" floppies. It came with 1 disk that
was dodgy... I couldn't find disks then... and that was the 90s... good
luck.

The Zenith MiniSport? I've got one, with about 7 minidisks.

I have 2 already. Wanna sell me 1 disk? I'm toying with the possibility of making
them. I actually used to have a single disk, but took it apart and threw it out like a
fool.
If yours had the external 3.5" drive, I could be interested on buying all of it.

There were a few other, incompatible ones!
I remember a cheap word processor with a 2.5" disk with a spiral track!
But, the Zenith (Mini-sport?) was the common one.
There were also 2.9"
and, of course, for PC there were 3", 3.25", 3.5", and IBM almost came out
with a 3.9"!

Smith Corona Data Disk--I did a decoder for one of those (Mitsumi?) for
a forensics client. Used a 2650 USART in sync mode with a bit of glue.
(9216 data separator) Worked just fine. Still have the ISA board.

Thank you.
I saw it at Comdex, and then never again.

I believe so--at least the Famicom replacement drive belts work in the
SCM Mitsumi drives. It's been something like 30 years since I fooled
with the things (still have one in the closet) but I recall the
interface was very simple--power, one line to start the spiral
(controlled a solenoid clutch) and the read/write data lines.
I think the Smith-Corona got something around 60K per disk,but I'd have
to check my notes. Using the USART, it was very simple (this was before
cheap MCUs).

Nintendo Famicom disk system uses some kind of
odd sized not swure disk.
Is that the same 2.8"? Mitsumi "Quick Disk" floppy used in the Smith
Corona Word Processor?

Ok the MS used 2" disks. I suspect only Fuji made them. I am that mental.
245 tpi 720kb. That thing was a beast in it's day. Like a LOTR dwarf champion or
something.
11:59 a.m.
There was the Amstrad floppy. I think it was 3". Hopefully didn't get out
of the UK.

The 3" floppy was available in single (flippy) and double-sided.
But, the two different driveswould not accept each other's disks! (You
could not use the flippy disks in the double-sided drive)
Besides the Amstrad, it was advertised and sold for AppleII and Coco,
under the name Amdek in USA, as an external two drive box.
I have heard that it was offered for other systems, but the ads that I saw
were offering only for Coco and Apple

Why would you say such a thing? Of course it got out of the UK and came
into Europe, where I could get them, use them, and enjoy them on my
Amstrad CPC 6128. I still keep them, plus a few more I've been getting
over the years, together with my original 6128, ant two others I've got
since then, plus a CPC 486 I also got later.
I was never lucky enough to own a PCW, but I still haven't lost the hope
to get one some day.

They were a good design. Exceptionally robust, and designed to be
posted directly, without an envelope, as the shutter can't be opened
by hand, only by the drive. Hitachi's mechanical design was IMHO
superior to Sony's of the 3½" diskette.

I need to check some boxes but I think I have 2 PCW9512s. I could be
persuaded to part with one. But you'd save money driving to Prague to
collect it, rather than shipping the 3 large boxes!
