Zusammenfassung:PCT No. PCT/SU87/00021 Sec. 371 Date Oct. 6, 1987 Sec. 102(e) Date Oct. 6, 1987 PCT Filed Feb. 5, 1987 PCT Pub. No. WO87/04843 PCT Pub. Date Aug. 13, 1987.An optical information carrier includes a cylinder (1) with a recording layer (2) and bushings (3,4) located at butt ends of the hollow cylinder (1) and insulating the recording layer (2) from the environment. A method for erasing information recorded on the optical carrier uses a high-frequency electrical discharge is produced inside the air-tight closed space (5) of the hollow cylinder (1). An optical storage device realizing the method includes an erasing unit (11) having a circuit for initiating a high-frequency discharge, which has electrodes (12,13) between which the optical carrier (10) is located so that the high-frequency discharge is initiated inside the closed air-tight space (5).
