Fred,
Just for the purpose of imaging the disks, is there any reason I cant treat
these disks like any other 5 1/4" cpm 360k disk?

Otrona is fairly straightforward for format conversion.
CP/M and MS-DOS. There might have been other operating systems for them,
but I didn't run into any.
They had 40 track and 80 track drives.
512 bytes per sector, so they can be done using Int13h, without even
needing Int1Eh.
10 sectors per track; inter-sector gaps were tight but not unreasonable.
I don't remember whether they were numbered 0 - 9 or 1 - 10
