No, kaypro disk format is double density on the system tracks too.  I'm
quite sure of this as I once dis-assembled and re-wrote the monitor ROM
code to use quad density drives.  (When it still cost money to get the
source code for it.)

When double density drives first came out there were a number of
systems that did make the system tracks single density.  The ones
that I knew of were all 8" floppies though, but I suppose someone
did it with 5 1/4 floppies too.
