Abstract: A rotary magnetic head inspection method for a double azimuth head where two magnetic heads of different azimuthal angles are arranged on a head base, includes the steps of: recording an inspection signal on a running tape by a magnetic head; reproducing the inspection signal by the magnetic head for checking the level of the reproducing signal; and reproducing the inspection signal by the other magnetic head for checking whether the magnetic head is correctly assembled onto a head base through judgement of the reproducing signal.
