Don,
No it's looks like just a single stepper motor. I found a diskette in one of htem.
It appears to be a standard disk. More about that in reponse to Will's message.

I was scrounging around last week and found a
pair of HH 5 1/4"
floppy drives that are marked "2.4" next to a disk symbol on the
front. Just out of curiousity I picked them up and checked
<http://marina.mfarris.com/floppy/Hitachi.html> and sure enough
they're 2.4Mb floppy drives! I've never heard of these before. Does
anyone know what the disk format is or where these are used? The
drives are Hitachi model FD532EIU. The label on them says that they're
made for IBM. They're in some sort of a plastic sled.
Do these drives have the typical single stepper to position the heads,
Joe, or is there an additional "vernier stepper" to more closely
position them as was the case with the Drivetec and (later) Kodak
drives? Both of those required preformatted disks that contained servo
tracks.
