  • Optical memory
    Patent number: 4829503
    Abstract: Disclosure is made of an optical memory wherein a cylindrical information carrier (2) is disposed in a stationary cylindrical container (14) filled with a liquid or gaseous medium transparent for the radiation flux emitted by a source (1) of modulated coherent radiation. The cylindrical information carrier (2) is equipped with a rotational drive. A recording coating (12) is applied on a tubular base (11) of the cylindrical information carrier (2). The cylindrical information carrier (2) is optically connected with the source (1) of modulated coherent radiation and with an addressing unit (3) arranged so that its optical elements can move axially with respect to the cylindrical information carrier (2).

  • Optical storage device
    Patent number: 4811327
    Abstract: Disclosure is made of an optical storage device wherein a cylindrical information carrier (2) with a recording medium (12) applied on a tubular base (9) is disposed in a stationary cylindrical container (3) having a window (4) in the lateral wall thereof. A lens (5) is secured in the window (4) of the cylindrical container (3) to let through the radiation flux from a source (1) of modulated coherent radiation. The cylindrical container (3) is filled with a liquid or gaseous medium transparent for the radiation flux. The length of this cylindrical container (3) is at least twice as long as that of the recording coating (12) applied on the tubular base (9) of the cylindrical information carrier (2) equipped with drives for rotation and axial motion.
