发明名称 METHOD OF REPRODUCING SIGNALS RECORDED ON A MAGNETOOPTIC RECORDING MEDIUM
摘要 The present invention is intended to improve the track recording density and track density of a magnetooptic recording medium to prevent the deterioration of characteristics due to the variation of reproducing power. After recording information signals on a magnetooptic recording medium having at least a reproducing layer, an intermediate layer and a record hold layer, the direction of magnetization of the reproducing layer is turned in the direction of an initializing magnetic field. The reproducing layer is irradiated with a laser beam and a reproducing magnetic field is applied to the same simultaneously to heat the reproducing layer in a temperature distribution so that a region remaining in an initialized state, a region to which information signals are transferred and a region magnetized in the direction of the reproducing magnetic field are formed. Magnetic signals are read from the region of the reproducing layer to which information signals have been transferred.
