    摘要： Disclosed is a method of recording information on a magnetooptical recording medium, which medium includes a first magnetic layer and a second magnetic layer having a lower Curie temperature and a higher coercive force at room temperature than those of the first magnetic layer. The second magnetic layer is exchange-coupled to the first magnetic layer. The first magnetic layer has a higher compensation temperature than the Curie temperature of the second magnetic layer. The method of recording information includes applying a magnetic field, which is modified in accordance with information from a magnetic head, to the medium to record information on the first magnetic layer and scanning the medium with a light beam to heat the medium to a temperature at least near the Curie temperature of the second magnetic layer so as to transfer the information recorded on the first magnetic layer to the second magnetic layer.

    摘要： When a vehicle moves into a radar prohibited area preset for the neighborhood of a facility that suffers adverse effects from radar waves, emission of radar waves is stopped, and a voice guidance such as “Radar monitoring is stopped” is sent to a speaker via a voice output unit. Moreover, during a period in which a vehicle is located in a radar prohibited area, an icon that indicates that a radar is being stopped, a mark that indicates an institution for which the radar prohibited area is set, and the scope of the radar prohibited area are displayed on a map image.

    摘要： Disclosed is a magneto-optical recording apparatus for recording an information signal on or for erasing an information signal from magneto-optical recording media by irradiating the magneto-optical recording media with a beam of light while applying a magnetic field thereto. The magneto-optical recording apparatus includes, as a magnetic field application device, a composite magnetic head which includes a first magnetic head capable of modulating a generated magnetic field in accordance with an information signal, and a second magnetic head capable of generating a constant magnetic field which is not associated with the information signal and capable of switching the direction of the constant magnetic field. This provides a magneto-optical recording apparatus which can use magneto-optical recording media for both light modulation type recording and magnetic field modulation type recording, and which ensures overwriting without increasing the overall size of the apparatus.
