Zusammenfassung:	PURPOSE:To make a ratio of a signal to noise S/N large by making a rotation angle of a plane of polarization large. CONSTITUTION:In the magnetic recording and reproducing method utilizing magnetoelectric transducing for transducing a change in a magnetically recorded magnetic domain pattern (recording contents) via its optical change into an electric signal (regenerative signal), the direction of an optical axis and a direction of magnetic flux to be generated from the recorded magnetic domain are arranged to have an angle other than right angles to each other. Moreover, magnetoelectric transducing by the magnetic Faraday effect is utilized. Thus, a large S/N as compared with a reproducing head utilizing the magnetic Kerr effect is obtained.
