Hi
I always considered track and cylinder to mean the same
for single sided.
For doule sided, Thre would be two tracks per cylinder.

I can't rememebr which machine it was, but one machine with 5.25" drives
claimed to have '80 track' drives. What they actually were were 40
cylinder, 2 head drives. So technically they did have 80 tracks, but it
caused a lot of confusion at the time.
-tony ISTR: the 8" drives at least as used in
tandy computers formatted out
to 77 tracks....
That's standard for all 8" drives--and it's "cylinders", please!
8"
drives can be double-sided with 2 tracks per cylinder.
