Abstract
In a recent paper by N. Hanasaki et al. [Phys. Rev. B 57, 1336 (1998)] a peak in the angular dependence of magnetoresistance found in several quasi-two-dimensional organic metals is attributed to small closed orbits on the side of the warped cylindrical Fermi surface when the magnetic field is nearly parallel to the conducting plane. We discuss contributions from different orbits on the Fermi surface to the conductivity and argue that the effect is caused by open trajectories lying near the self-crossing orbit, rather than by the small closed orbits.
