Abstract
A recording and retrieval device is disclosed. The recording and retrieval device generates an electron beam which selectively exposes portions of a film to thereby record digital data on the film. An input circuit adjusts a characteristic of the electron beam selectively expose portions of the film. An anode target is exposed to the electron beam through exposed portions of the film and arranged to generate anode current indicative of digital data stored on the film. A support may secure a sheet of film such that electrons pass through exposed portions of the film. An output circuit operatively coupled to the anode couples the anode current to an external output device.

An apparatus for recording and retrieving digital data on a film comprising:
- a vacuum enclosure having an input and an output;
- an electron gun disposed at the input of the vacuum enclosure and arranged to discharge a beam of electrons into the vacuum enclosure;
- an input circuit operatively coupled to the vacuum enclosure and the electron gun, and arranged to adjust a characteristic of the electron beam to selectively expose portions of a film to thereby record digital data on the film without moving the film;
- a target disposed at the second end of the vacuum tube and arranged to generate signals indicative of stored digital data when exposed to electrons from the electron beam passing through exposed portions of the film.
An apparatus for recording and retrieving digital data on a film comprising:
- a vacuum tube having first and second ends;
- an electron gun disposed at the first end of the vacuum tube and arranged to discharge a beam of electrons into the vacuum tube;
- an input circuit operatively coupled to the vacuum tube and the electron gun,
- the input circuit being arranged to adjust a characteristic of the electron beam to selectively expose portions of a film to thereby record digital data on the film without moving the film;
- the input circuit being arranged to maintain the characteristic of the electron beam to pass electrons though exposed portions of the film to thereby read digital data on the film without moving the film;
- a target disposed at the second end of the vacuum tube and arranged to generate signals indicative of stored digital data when exposed to electrons from the electron beam passing through exposed portions of the film.

- a support arranged to secure a sheet of film between the second end of the vacuum tube and the anode target such that electrons from the electron beam pass through exposed portions of the film when the film is secured to the support;
- and
- an output circuit operatively coupled to the anode target and arranged to couple the anode current generated by the anode target to an external output device.
