Abstract
A magneto-optical recording apparatus including a magnetic head applying a magnetic field to a magneto-optical recording medium in a region wider than a minimum bit record area thereby forming a magnetic field region, a beam source and an optical system forming on the magneto-optical recording medium a laser beam spot defining the minimum bit record area, a modulation unit for modulating at least one of the magnetic field and the laser beam thereby forming the laser beam spot within the range of the magnetic field region, and a mechanical unit 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. The slider rails (11) each have a width of at least 2 mm, so as to increase the flying height of the slider (1017) over the medium.
