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.
An RX02 drive can reformat an RX01 disk as RX02.
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, "4.3.3.5 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.
