Abstract | A magneto-optical recording medium characterized in that a magneto-optical recording layer (6), an intermediate layer (7) comprising a magnetic thin film whose optical reflection factor is 50 % or more, and an auxiliary layer (8) which has a lower coercive force in comparison with the recording layer at a room temperature and has the Curie point higher than that of the recording layer and which is vertically magnetized are formed in this order on a substrate (4, 15). The size of an initializing magnet can be reduced, and a stable recording can be realized.
Support d'enregistrement magnéto-optique caractérisé par le fait qu'une couche d'enregistrement magnéto-optique (6), une couche intermédiaire (7) comprenant une couche magnétique mince dont le facteur de réflexion optique est de 50 % ou plus, et une couche auxiliaire (8) verticalement magnétisée qui présente une force coercitive inférieure à une température ambiante par rapport à la couche d'enregistrement et un point de Curie supérieur à celui de la couche d'enregistrement, sont formées selon cet ordre sur un substrat (4, 15). La taille de l'aimant d'initialisation peut être réduite et un enregistrement stable peut être obtenu. |
