摘要： A magneto-optical memory device is provided with a recording track having a recording film and a guide track wherein a perpendicular magnetic film, whose magnetization direction is arranged in one direction, is formed, the recording track and the guide track being alternatively disposed. A recording operation is carried out using a circular magnetic field generated from the perpendicular magnetic film by projecting a light beam only on the recording track so as to raise the temperature of the recording film. When erasing, the light beam is projected on the recording track and respective portions of the guide tracks located on both sides of the recording track so as to raise the temperature thereof. As the temperature rises, the magnetization of the perpendicular magnetic film becomes smaller, and an erasing operation is therefore performed using an external magnetic field.

摘要： A magneto-optical recording medium is consisted of a recording layer, a readout layer and a writing layer. The readout layer is made of rare earth-transition metal alloys wherein an easy magnetization axis is parallel to the recording layer at room temperature, and the easy magnetization axis is perpendicular to the recording layer as the temperature of the readout layer is raised above a predetermined temperature by irradiating thereon with a light beam. The writing layer is made of rare earth-transition metal alloys having such coercive force that a magnetization direction thereof is switched by an external magnetic field at room temperature and Curie temperature that is above Curie temperature of the recording layer. With the above arrangement, an overwriting function can be achieved by adjusting a light intensity of the light beam so that the temperature falls within the range between the Curie temperature of the writing layer and the Curie temperature of the recording layer, or above the Curie temperature of the writing layer.

摘要： An optical recording medium, which is used as an optical disc, optical card or the like for optically recording, reproducing, erasing and the like, includes a center substrate having formed on at least one side thereof recesses and/or protrusions. Recording films are formed on both sides thereof and transparent protective plates bonded to these recording films respectively. This arrangement substantially eliminates warping of the substrates constituting the optical recording medium and exfoliation of substrates or the like even when the optical recording medium is subjected to sudden changes in temperature. This optical recording medium demonstrates enhanced optical performance and protective effect. The selecting of the transparent protective plate is simplified because the forming recesses and/or protrusions is not a factor. By producing an optical recording medium utilizing the above features, the carrier-to-noise ratio and isotropy of the medium is improved.
