Let D be a non-displaceable disk in an annulus A. Suppose that g is acompactly supported Hamiltonian which preserves D with translation number n. Weshow that Hofer's norm |g| is bounded from below by cn for a certain constantc. We also give example of such Hamiltonian which is more efficient than theobvious rotation of D.
