Drift motion of a twisted domain wall (TDW) in a strong magnetic field circularly polarized in the plane of a perpendicularly magnetized film is considered. The twisted structure reduces the threshold for the regime of stationary motion of a TDW (on both the velocity of motion and frequency of the rotating field) in comparison with a one-dimensional DW of the Bloch or Néel type. The dependence of the boundary of optimum (from the experimental viewpoint) observation of drift of a TDW in the regime of stationary motion on the ratio of the width of a Bloch line to the thickness of the film has been determined.
