ABSTRACT:
A magneto-optical recording/reproducing device having a slider provided with a magnetic head. The slider floats over a magneto-optical disk when the magneto-optical disk is in rotation. The slider is supported by a suspension. A depressing force is exerted on the slider vertically by the suspension. The depressing force is adjusted by an adjustment device so that the depressing force due to the suspension increases as the slider shifts to an outer part of the magneto-optical disk from an inner part. Thus a floating gap between the slider and the magneto-optical disk becomes substantially constant irrespective of a radial position on the magneto-optical disk and a magnetic field intensity applied onto the magneto-optical disk from the slider (the magnetic head) becomes constant. As a result, stable recordomg, reproducing and erasing operations can be carried out.
