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.
摘要翻译：磁光调制光的方法包括以下步骤：在其传输路径上线性偏振光，将磁光效应元件放置在偏振光的传输路径上，其中元件的自发磁化方向与传输路径平行，当不存在所施加的磁场的情况下，当偏振光的偏振平面旋转以由磁光效应元件旋转以呈现第一旋转位置时，偏振光被调制成第一光分量，将磁场施加到磁光效应元件，元件的内部磁化在垂直于传输路径的方向上定向，当偏振光的偏振光偏移到第二旋转位置时，偏振光被第二光分量调制成第二光分量存在所施加的磁场。根据该方法，在传输路径垂直于所施加的磁场的条件下对光进行调制，从而可以将传输路径引导到分别垂直于施加磁场的方向的各种不同方向中的一个方向领域。

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.

摘要： An actuator unit 100 which moves a light reflection element 32 in a predetermined optical path-switching-position includes a mover 120 to which the light reflection element 32 is fixed, and a fixed part body 110 including an E-shaped yoke 113. When the mover 120 is located at one end in its moving range, the posture of the mover 120 is specified by magnetic attraction forces in two directions orthogonal to each other which are generated between one end portion 113a yoke 113 and an orthogonal part 113c of the E-shaped, and the mover by a permanent magnet 121 and an electromagnet 118, whereby a tilt of the mover 120 can be prevented.
