Magneto-optical recording medium for magnetically induced super resolution

A magneto-optical recording medium having a plurality of tracks and comprising:

• a substrate;
• a recording layer made of a first magnetic material upon which recording domains are formed during data writing and data saving, said first magnetic material having an inhibition force, to inhibit movement of a domain wall of each of said recording domains formed along a track in said recording layer, which is larger than a contraction force of a half bubble which is formed in said recording layer when a track adjacent to the track containing the recording domain is heated during erasing or recording;
• a switching layer made of a second magnetic material, said second magnetic material has a Curie temperature no greater than 200.degree. C. and has perpendicular magnetic anisotropy;
• a readout layer made of a third magnetic material upon which magnetic states of the recording domains are copied from said recording layer, said third magnetic material has a Curie temperature of at least 300.degree. C. and a coercive force which is no greater than 1 kOe at room temperature;
• wherein said recording layer, said switching layer and said readout layer are formed on said substrate such that said readout layer is formed at a side of said recording medium in which light is received during erasing and recording;
• and
• wherein said readout layer has a coercive force which is lower than that of said recording layer at room temperature, and the Curie temperature of said switching layer is lower than that of said recording layer and that of said readout layer.
