Magneto-optical recording system

摘要: A magneto-optical recording medium having an easy axis of magnetization in a direction perpendicular to the film surface. readout layer 6, reflection 8 and 5 are sequentially disposed incidence read-out light, thereby increase output reproduced. Layer 6 provides relatively large Kerr rotational angle ???K has low curie point Tc coercive force Hc. The reflecting may be thin non magnetic metal only, or it contain mixture metals (as Fig. 9, not shown).
