The 2 belt-drive capstan flywheels in an auto-reverse cassette mechanism
are different sizes. (Motor drive pulley will be in the small loop end
of the belt in illustration above.)

How does that result in the same tape speed in both directions?

Confused...

Presumably the belt speed changes, or the capstains themselves are
different diameters.
