  • Magneto-optical readout method and magneto-optical readout head and method for making same
    Patent number: 5920538
    Abstract: A magneto-optical readout head for reading out magnetically stored data has a high optical quality substrate and a transducer applied to the substrate formed by a Faraday rotator and a Kerr rotator, with the Kerr rotator facing the magnetic storage medium. The substrate can be provided with a shape for magnifying the domain structures of the Kerr rotator and the Faraday rotator. Linearly polarized light is passed through the substrate and the polarization vector thereof is rotated by the Faraday rotator upon passage through the Faraday rotator and the light is reflected at the Kerr rotator, and is provided with an additional rotation upon reflection.
