They don't have sectors and tracks in the usual sense. Track 16 (on a
48tpi drive; track 32 on a 96tpi drive) has a cat's-eyes pattern. Track 01
or track 34 (02 or 68 on 96tpi) has an index burst pattern (a burst of
signal which is 200 microseconds after the index hole, assuming the speed
is correct).
