OPTICAL-MECHANICAL MEMORIZING DEVICE.

摘要

The device comprises a cylindrical information carrier (1) consisting of a tubular base with a recording layer (2) and located coaxially inside a cylindrical casing (4). The device further comprises an electromagnetic radiation source (7). Mounted on the end faces of the cylindrical carrier (1) are flanges (8, 9), one of which carries the working organ (10) of a drive (13) for rotation and axial movement of the cylindrical carrier (1). The casing (4) consists of two hermetically interconnected parts, one of them being a removable container (11). The drive (13) for rotation and axial movement is located outside the casing (4) containing, inside, an immersion liquid (14). The device relates to the computer technology and may be used in the external memory of electronic computers.
