Are you thinking of the different position of the index hole in 8"
disks?  That differentiates single-sided from double-sided, not
densities.

  My
 understanding is that unlike the 5-1/4 disks, the 8 in. media
 is the same for the single and double density, just higher
 quality. In fact, I punch a new index window in some of my
 double density 8 inch floppies and I've been using them, with
 no troubles, as single density.
  The 5-1/4 disk are a different story. Single/Double don't mix. 
Sure they do.  Same coercivity.  There might be a difference in quality
on early ones, but barring flaws in the emulsion coating, they're
interchangeable, and you can always use DD as SD.

It's single/double density and high density that are different.
