ABSTRACT:
In a magneto-optical recording apparatus, since a magnetic field is not generated in a data recording impossible area in order to lower power consumption, sufficient intensity of the magnetic field can be obtained at the head of a data recording area. In the case of recording information data in a data recording area of a magneto-optical recording medium, a magnetic field is generated in a data recording impossible area which exists between a pit formed at the latest end side of the data recording impossible area and the head of a data recording area located just after the data recording impossible area, without generating the magnetic field during the time of scanning a laser beam from the head of a data impossible area located just before a data recording area and a pit formed at the latest end side of the data recording impossible area. Thereby practically sufficient intensity of the magnetic field can be steadily and surely obtained at the time of recording information data in the data recording area. Thus a magneto-optical recording apparatus and a magneto-optical recording method which is able to cope with to high-density recording with low power consumption can be realized.
