Zusammenfassung:	PCT No. PCT/SU87/00017 Sec. 371 Date Oct. 6, 1987 Sec. 102(e) Date Oct. 6, 1987 PCT Filed Feb. 5, 1987 PCT Pub. No. WO87/04840 PCT Pub. Date Aug. 13, 1987.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.
