<p>An optical memorization device in which a cylindrical information carrier (2) with a recording layer (12) applied on a tubular support (9) is mounted inside a stable cylindrical container (3) provided, in its side wall, with a window (4). In the window (4) of the cylindrical container (3) is fixed a lens (5) for the passage of the modulated coherent radiation flux from a source (1), the cylindrical container (3) being filled with a liquid or gaseous medium which is transparent to the flux, and the length of the container being at least twice as large as that of the recording layer (12) applied on the tubular support (9) of the cylindrical information carrier (2) provided with drives for its rotation and axial displacement.</p> |
