Does that imply that the flux density on side one
differs from side zero
at the same cylinder? If so, why.
The heads are not actually directly opposed. The head on side 1 is slightly
closer to the spindle, by 2.117 mm on standard 5.25 inch drives. This
makes the tracks on side 1 about 13.3 mm shorter than those of side 0.
Since side 1 has the same number of flux transitions in a shorter space,
the flux density is higher.
