Abstract
An optical storage device (data) includes an optical data carrier (1) placed inside a container (6), which is full of immersion liquid (9). At least two fixed optical elements (8) are placed on transparent wall sectors of the referred container (6), and correspond to optical heads (10), where each head includes a source (11) of modulated monochromatic radiation, a moving optical element (12), a beam separator (13), and a light detector (14). The optical storage device is connected to the external information processing system (computer) via a control unit (18), which is connected to the light detectors (14) and to the sources (11) of modulated monochromatic radiation. Each light detector (14) is connected to an auto focusing unit (15), whose output is kinematically connected to the moving optical element (12), while one of the light detectors (14) is connected to an orbit transformation unit (17) that is connected to an orbit tracking unit (16). The control unit (18) is connected to the orbit transformation unit (17), and the orbit detection unit (16), which in turn is connected to the information administration unit (20), is kinematically connected to the optical data carrier (1).
