Abstract

PURPOSE:To miniaturize the titled device by providing a yoke plate along a circle centering the rotary shaft of an optical disk, holding a turning member freely rotatably on a same shaft as the optical disk, and providing a coil at an outer end to interlink a magnetic field generated in the yoke plate. CONSTITUTION:Optical units 9 and 10 are movably held on the rotational center line of an optical disk, the yoke plates 20, 24 and 25 along the circle concentric to the rotary shaft of the optical disk in a frame 1 and magnetic field means 26-29 to magnetize the yoke plates are equipped, held freely rotatably on a same shaft as the optical disk in the frame 1, coils 18 and 19 to interlink the yoke plates are held, a turning member 42 equipped with a gear 39 to transmit a power for moving to the optical units 9 and 10 are provided. The relation of the rotational angle of the turning member 42 and the moving stroke of the optical units 9 and 10 are decided by the diameter of the gear 39, the moving stroke of a magnetic sensor of the outer end of the turning member 42 and be largely obtained for the moving stroke of the optical units 9 and 10. Thus, the device can be miniaturized.
