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

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.
