    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： Film of a known refractive index whose thickness is to be measured is illuminated by a white light beam. Two wave fronts from both sides of the film are directed to an interferometer. The wave fronts are out of phase in accordance with the thickness of the film. The two wave fronts are amplitude-split, respectively, by the beam splitter of the interferometer. Two of the split wave fronts are tilted by tilting means in the interferometer. The other two split wave fronts, as well as the two tilted wave fronts, are directed to an interference surface. Thus, there is formed a white interference pattern on the interference surface. The white interference pattern has a middle peak and two side peaks. The space interval between these peaks is measured by a scanner. By knowing the peak-to-peak interval, it is possible to discriminate the space interval between both sides of the film.
