<p>A magnetoelectric mechanism for moving an optical head comprises a double-arm lever (1) with an optical bead (4). Cylindrical windings (9, 10) embracing, with gaps (11, 12), an annular yoke (13) are mounted in openings (7, 8) in the bodies of the arms (3, 5) of the lever (1). A further two annular yokes (14, 15) are mounted symmetrically in relation to the plane of symmetry of the annular yoke (13) and coaxially to it and are provided with permanent magnets (16, 17, 18, 19) mounted on them in diametrically opposite positions and in immediate proximity to the cylindrical windings (9, 10).</p> |
