ISO 9660 is A standard for how data can be written to a storage
medium. It has everything to do with a file system. It _IS_ a
file system (among other things).

ISO 9660 specifies many things:
directory structure
permitted filenames
etc

It does not specify that data will be written on a spiral
track in aluminum pits under a polycarbonate substrate.

Any file system can be imposed on the CdRom physical structure,
just as any file system can be imposed on a magnetic disk.
You can have ISO 9660 on a floppy (and I have one).

Most CdRoms I've seen recently do not carry the ISO 9660
logo, and are not 9660. They are HFS, MsDos, etc. Looking
at a recent MEI catalog, less than half the advertised CDs
show the 9660 logo.

This may be my ignorance or lack of recent experimentation.
I ask this very question in another post, so won't repeat
it here. What kind of MsDos disk did you get? A 1.44 HD 3.5"
floppy? 720K 3.5" floppy? Or something else?
