摘要:
A magneto-optical recording and/or reproducing apparatus includes an optical head for providing a light spot for recording, reproducing and erasing of a magneto-optical disc, a magnetic head which is disposed at a position opposing the optical head with the magneto-optical disc therebetween and which provides a magnetic field for recording and erasing while maintaining a substantially constant distance from the magneto-optical disc by effecting a lift obtained by an air flow generated by the rotation of the disc, a loadbeam which has the magnetic head on its one end and serves to provide a force caused by elastic deformation to the magnetic head to thereby be balanced with the lift thus obtained, and a moving mechanism connected to the loadbeam. Approaching or evading the magnetic head to or from the magneto-optical disc can be realized by deforming the moving mechanism.
