<p>Apparatus including a magnetic head (1012) applying a magnetic field to a magneto-optical recording medium (1) in a region wider than a minimum bit record area thereby forming a magnetic field region, a beam source and an optical system (2, 3, 4, 5, 6) forming on the magneto-optical recording medium a laser beam spot defining the minimum bit record area, a modulation unit (1014) for modulating at least one of the magnetic field and the laser beam thereby forming the baser beam spot within the range of the magnetic field region, and a mechanical unit (1016) for moving the magnetic field region and the laser beam spot relative to each other on the magneto-optical recording medium while the modulation unit is under operation, the magnetic head being floated to be spaced apart from the surface of the magneto-optical recording medium by a distance not smaller than 10 mu m while the mechanical unit is under operation.</p> |
