摘要： PROBLEM TO BE SOLVED: To obtain a reproduced output in which crosstalk is small and whose level is sufficiently high even when magneto-optical recording area where embossed pits are formed and the area where the pits are not formed are made adjacent by making a magnitude of a phase difference to be generated by the double refraction of a substrate and the magnitude of a phase difference to be generated by the Kerr elliptic effect of a recording layer within specific ranges. SOLUTION: Recording layers are formed on a substrate on which embossed pits indicating information are formed and the layers are made to have a groove recording format. In intra-surface directions, a direction orthogonal to a recording track and a direction being along the recording track are respectively defined as an x direction and a y direction. When a phase difference to be generated by the double refraction of the substrate and a phase difference to be generated by the Kerr elliptic effect in the phase difference between the deflection component of the x direction and the deflection component of the y direction of the return light of the reproducing light reflected on the recording layer are respectively defined as ϕbr and ϕMO, these are made to satisfy -20 deg.C

摘要： PROBLEM TO BE SOLVED: To enhance the recording density of a recording medium to have equal to or higher than a resolving power to be determined with the wavelength of reproducing light by impressing a magnetic field to a magnetic recording medium so that magnetization is directed in a fixed direction in the region of one part in the spot of reproducing light when an information signal is reproduced by irradiating the medium with the reproducing light. SOLUTION: When a magneto-optical disk is irradiated with reproducing light La from the side of a reproducing layer 4a of the disk and also a reproducing magnetic field Hr is impressed on the a region icluding the spot S of the reproducing light by the reproducing light La while rotatingly driving the disk, the reproducing layer 4a of a low temp. region B1 is initialized by the reproducing magnetic field Hr and the magnetization of the reproducing layer 4a of the low temp. region B1 is always directed to a fixed direction regardless of the magnetization direction of a recording state holding layer 4c and, as a result, the low temp. region B1 becomes a so-called front mask by masking the front side of the scanning direction of the spot S of the reproducing light. In a high temp. region B2, magnetism of an intermediate layer 4b disappeares and an exchange coupling in a recording layer is cut and the reproducing layer 4a is always magnetized in the direction of the reproducing magnetic field Hr.
