<p>An optical memorizing device comprises an optical information carrier (1) placed inside a container (6) filled with an immersion liquid and provided, on transparent sections of its walls, with at least two optical elements (8) conjugating with optical heads (10), each of which comprises a source (10) of modulated coherent radiation, a movable optical element (12), a light divider (13) and a photoreceptor (14). The optical memorizing device is conjugated with an external information computing system through a control unit (18) connected to the photoreceptors (14) and to the sources (11) of the modulated coherent radiation. Each photoreceptor (14) is connected to an autofocusing unit (15), the output of which is kinematically connected to a movable optical element (12), whereas one of the photoreceptors (14) is connected to a recording track switching unit (17) connected to a track following unit (16). The control unit (18) is connected to the recording track switching unit (17) and to the track following unit (16) connected in turn, to an information addressing unit (20) kinematically connected to the optical information carrier.</p> |
