We report on the formation of two-dimensional array of two-/four-armed chiral surface reliefs of azo-polymers by irradiation of a rotating petal-shaped beam with zero orbital angular momentum. Such chiral surface relief array will pave the way towards advanced rewritable ultrahigh-density optical data storages.
