Sorry, I was slightly imprecise - I guess I should have said '_blank_
floppies that an RX02 can use to write double-density RX02 floppies can be
created on anything that can create RX01 floppies'. But the bottom line is
the one I gave: blank floppies which one can use in an RX02 can be created on
anything that can make RX01 floppies.

Right, that was what I meant with:
> an RX02 is fed RX01 floppies, which it then writes in the unique-to-DEC
> double density RX02 format
If anyone wants to see the gory details, "RX02 Floppy Disk System User Guide"
(EK-RX02-UG-001) has them on pg. 4-41, "184.108.40.206 Set Media Density (100)".
Sections 1.5.2 ("Recording Scheme") and 1.5.3 ("Logical Format") give the
technical details of the floppy content in quite complete form.
