A problem of the spectrum of the collective periodic motion of vortex domain walls in a system of parallel ferromagnetic nanostripe is theoretically solved. The magnetic subsystems of stripes are coupled by the magnetostatic interaction. The effect of the distribution of vortex core polarities and chiralities on the character of periodic motion and the spectrum of collective modes of the nanostripe magnetization is discussed. Analytical expressions for the dispersion law and damping parameter of the collective periodic motion of vortex domain walls are obtained.
