ABSTRACT:
A magneto-optical recording medium in which the inside of grooves formed along recording tracks is a signal recording area in groove recording, and the domain wall displacement detection method is employed; and a curvature radius R1, in the cross section perpendicular to the recording tracks, of a shoulder portion of a land separating the grooves that is adjacent to the groove is 30 nm or less and a curvature radius R2, in the cross section perpendicular to the recording tracks, of the inside edge portion of the groove for the recording that is adjacent to the land is 20 nm or more, so that a wide recording power margin can be obtained, the jitter can be improved, and the error rate can also be improved.
