摘要： A surface of a magneto-optical recording medium of the present invention is textured with fine and physical protrusions and recessions. The shapes of physical protrusions and recessions vary at each radial locations on the medium such that, for example, rough protrusions and recessions are formed in inner parts of the recording medium and fine protrusions and recessions are formed in outer parts thereof. Therefore, floating force given to a floating head from the medium being rotated based on the constant angular velocity method through an air layer in the outer parts equals floating force in the inner parts. Consequently, since the floating height of the floating head becomes constant irrespective of radial locations on the medium, information can be recorded under constant recording conditions, permitting the accuracy of the recording to improve. Regarding a method for processing the surface of a magneto-optical recording medium relating to the present invention, for example, a texture tape whose roughness is large is used in inner parts of the medium while a texture tape whose roughness is small is used in outer parts thereof. As a result, a magneto-optical recording medium having the above characteristics is produced.

摘要： A magneto-optical recording medium according to the present invention comprises a recording layer in which information is to be recorded; and a reproducing layer to and from which information recorded in the recording layer is to be transferred and read out. The magneto-optical recording medium is arranged such that, at room temperature, the width of a stable magnetic domain of the reproducing layer is wider than the width of the recorded magnetic domain formed in the recording layer at the time when information has been recorded therein, and that, at temperature exceeding a predetermined value, the relationship between these widths is reversed. Accordingly, upon irradiation of a light beam, there is transferred and reproduced, to and from the reproducing layer, the magnetic domain of only that portion of the recording layer corresponding to the center portion of the light beam where the temperature of the reproducing layer exceeds the predetermined value. It is therefore possible to provide a magneto-optical recording medium in which information can be recorded with high density and which is suitable for recording image information or the like for which a large recording capacity is required.
