Anisotropy acts to select preferentially certain well defined beam trajectories on the surface of a disc delay line. Selection is ascribed to the curvature of the slowness surface. An anisotropic optical design formalism is developed and applied to the diagnosis of earlier experimental observations of large differences in loss on three rectangular recirculating loops.
