    • An ink sheet having an ink layer, containing ink to be molten by heat generated by its absorption of received light, includes a magnetic layer being magnetized to have a preset magnetic pattern. The direction of polarization of the reflecting light varies depending on a state of the magnetization on the magnetic layer when part of the received light is incident on and reflected from the magnetic layer. The ink sheet is combined with a printer in which a recording medium and the ink sheet are coupled together, and ink is transferred to the recording medium when the ink sheet receives light. The printer includes optical heads for projecting a light beam upon the ink sheet while moving in the width direction of the ink sheet, sensors for sensing a state of polarization of the light beam reflected from the ink sheet, and actuators for adjusting an irradiating position of the light beam on the ink sheet on the basis of a state of polarization of the reflecting light that is sensed by the sensor.

    • A floating head for use with a recording apparatus of magneto-optical memory type comprising a floating body which is provided in the vicinity of a rotating optical recording medium and which is made afloat by an air stream created by the rotation of the recording medium, an objective lens which is fitted in an optical path forming aperture in the floating body and which permits converging light from a light source to be focused on a focusing plane of the recording medium, and a coil which is installed in the vicinity of the optical path forming aperture in the floating body and which forms a magnetic field toward the focusing plane of the recording medium. The floating body is made of a soft magnetic material and is provided with a rim made of a soft magnetic material which is formed along the peripheral edge of the optical path forming aperture on the side closer to the optical recording medium and which projects toward the same. The rim is tapered in such a way that its wall thickness decreases gradually toward the center of the optical path forming aperture.
