One way is to use different labels on the same scales
tiktop = {#, #} & /@ Range[10];
tikbot = {#, 1/#} & /@ Range[10];
Plot[x, {x, 1, 10},
FrameTicks -> {{Automatic, Automatic}, {tiktop, tikbot}},
Frame -> True, Axes -> False
]
Another way is to manually construct the axis using a combination of
differently-oriented lines & text, and placing it using Epilog. This
second way is very, very fiddly.
