Lamina recording apparatus.

摘要

A data recording device in which an emitter (4) normally an electron gun, is mounted within an evacuatable tube (6) into which a sensitive recordable film (39) may be introduced so that no part of the tube interposes between the emitter and the area (14) of the film to be recorded. The film may be held on a grid (19) in the tube or on a separate platen (42). The invention avoids the interposition of glass and coating material between the emitter and film and so can record with finer detail on the film. Also the device is very suitable for fast film handling by conveying the film on a gas stream into the tube.
