PURPOSE: To improve the C-N ratio, jitter, etc., in a new method in which reproduction or recording and reproduction are carried out particularly with a violaceous laser (350-450 nm) and/or reproduction or recording and reproduction are carried out particularly with a field lens having a numerical aperture N. A. of >= 0.7 in a magnetic ultra-resolution reproducing method having a process for transferring the recording magnetic domain of a recording layer to a reproducing layer. CONSTITUTION: The magneto-optical recording medium has at least a reproducing layer 1 and a recording layer 3. The recording layer 3 has at least 1st and 2nd magnetic films 31 and 32 each comprising a rare earth-transition metal magnetic film whose composition at room temperature ranges from a compensated composition to a transition metal-predominant composition. The recording medium exhibits excellent magnetic characteristics in a wide temperature range.
