摘要： A magneto-optical recording apparatus which records information through the processes of: first irradiating a light beam onto a magneto-optical recording medium having a recording film; and next applying an external magnetic field that is inverted in response to a recording signal onto the recording film while continuing the first process. In the above arrangement, the intensity of the light beam is dropped upon inversion of the external magnetic field so that information is not recorded. The intensity of the light beam is raised during non-inversion of the external magnetic field so that information is recorded. Further the magneto-optical recording apparatus is provided with a light intensity control device for varying the intensity of the light beam dependent of the lengths of recording bits so that the high-temperature area of the recording film is not widened. Since the width of the recording bits is uniformly maintained, the remaining of the recording bit after overwriting operation can be reduced; thus, the signal quality in reproduction can be enhanced.
摘要翻译：一种磁光记录装置，其通过以下处理记录信息：首先将光束照射到具有记录膜的磁光记录介质上; 并且接着在继续进行第一处理的同时将响应于记录信号反转的外部磁场施加到记录膜上。在上述布置中，光束的强度在外部磁场反转时下降，从而不记录信息。在外部磁场的非反相期间，光束的强度升高，从而记录信息。此外，磁光记录装置设置有光强度控制装置，用于根据记录位的长度改变光束的强度，使得记录膜的高温区域不会变宽。由于记录位的宽度被均匀地保持，所以可以减少重写操作之后的记录位的剩余部分。因此，可以提高再现中的信号质量。

摘要： A magneto-optical disk has a recording layer whereon recorded bits are formed by the magnetic field modulation method and a readout layer whose axis of easy magnetization is parallel to the recording layer at room temperature, and varies to be perpendicular to the recording layer within a predetermined temperature range between room temperature and the Curie temperature. During reproduction of the recorded bits the first semiconductor laser emits a heating-use light beam to form the first light spot on the readout layer Thus, a ring-shaped region corresponding to the predetermined temperature range exhibits perpendicular magnetic anisotropy and the recorded bits are copied from the recording layer onto the ring-shaped region. As the first light spot is shifted, the ring-shaped region as a readout window of recorded bits is also shifted. Further, the second semiconductor laser emits a reproduction-use light beam such that the second light spot is formed on the readout layer to overlap the first light spot at a rear portion thereof. Consequently, only one recorded bit copied onto the rear portion of the ring-shaped region can be reproduced; therefore, high-quality reproduced signals can be obtained from the magneto-optical disk having information recorded with high density.

摘要： A magneto-optical storage device having a configuration wherein a first AlN film, a Pt/co multi-layer film formed by alternately depositing Pt and Co, a second AlN film, and an Al reflective film are successively laminated on a substrate in this order. Assuming that respectively the thickness of the first AlN film is .delta.AlN (1); that of the second AlN film is .delta.AlN (2); that of the Pt single layer is .delta.Pt; that of the Co single layer is .delta.Co; and the total thickness of the Pt/Co multi-layer film is .delta.Pt/Co, each thickness of those layers is set to range within: 50 nm .ltoreq..delta.AlN (1).ltoreq.200 nm; 120 nm.ltoreq..delta.AlN (2).ltoreq.140 nm; 0.6 nm.ltoreq..delta.Pt.ltoreq.1.0 nm; 0.3 nm.ltoreq..delta.Co.ltoreq.0.6 nm; and 15 nm.ltoreq..delta.Pt/Co.ltoreq.20 nm. In accordance with the above arrangement, it is possible to greatly widen the tolerances of the film thicknesses of the first and second dielectric layers for obtaining a predetermined reflective index as well as a maximum Kerr rotation angle. Consequently, without strictly controlling the film thicknesses of the first and second AlN films, a magneto-optical storage device with stable performance suitable for practical use can be produced easily.
