    摘要： A method of magneto-optically modulating light comprises the steps of linearly polarizing the light on its transmission path, placing a magnetooptic effect element on the transmission path of the polarized light with the spontaneous magnetization direction of the element being parallel with the transmission path, the polarized light being modulated into a first light component when the plane of polarization of the polarized light is rotated to assume the first rotational position by the magnetooptic effect element in the absence of the applied magnetic field, applying the magnetic field to the magnetooptic effect element with the internal magnetization of the element being oriented in a direction perpendicular to the transmission path, the polarized light being modulated into a second light component when the plane of polarization of the polarized light is shifted to a second rotational position by the magnetooptic effect element in the presence of the applied magnetic field. According to the method, the light is modulated under the condition that the transmission path is perpendicular to the applied magnetic field, thereby making it possible to direct the transmission path in one of a variety of different directions respectively perpendicular to the direction of the applied magnetic field.

    摘要： A method of manufacturing a medium having a magnetic pattern, comprises the steps of forming a first groove in a substrate by photoetching, and forming in the first groove or in a portion of the substrate adjacent to the first groove by the photoetching a second groove of different depth than the first groove. The first and second grooves are then filled with a ferromagnetic substance so that the ferromagnetic substance in the first groove is different in thickness from the ferromagnetic substance in the second groove. The ferromagnetic substance is then magnetized to produce magnetic field intensity distribution based on the thickness of the magnetized ferromagnetic substance.
