摘要： An add-on module (14) for a contact printer used to manufacture a motion picture. The module (14) enables the printing of a digital optical soundtrack on motion picture film from a sound negative (16) using a conventional contact printer (142). The module (14) includes a guide roller (24), a sprocket (26) and a main roller (34). Unexposed film (18) is placed in contact with the sound negative (16). The sound negative (16) is placed in contact with the guide roller (24) and the sprocket (26) and the unexposed film (18) is placed in contact with the main roller (34). The module (14) further includes a fiber optic light source (56) positioned adjacent to the sound negative (16) for exposing the film and forming the digital soundtrack. In addition, air pressure (64) is used to maintain contact between the sound negative (16) and the unexposed film (18) to ensure an accurate reproduction of the digital soundtrack. The digital soundtrack is formed on a portion of the positive print (18) which includes an area between each of the sprocket holes. In addition, the digital soundtrack extends from each sprocket hole to the edge of the positive print (18) on both sides of the print.

摘要： A rigid transparent cylinder (56) is rotated about its axis of symmetry at a relatively high rate of speed by means of a motor (58). Around a portion of the circumference of the rotating cylinder is wrapped a flexible imaging medium such as photographic film (14), to which is applied longitudinal tension through means of a film transport. The film conforms to the curvature of the drum, but is held a small distance above the surface of the cylinder in equilibrium between the aerodynamic forces created by the rotating cylinder and the applied tension of the film transport, thus effecting a compliant surface air bearing. A stationary lamp (60) within or behind the transparent cylinder passes light through the cylinder to project an image from the film onto a scanning element by use of a conventional optical system.

摘要： A rigid cylinder (56) is rotated about its axis of symmetry at a relatively high rate of speed by means of a motor. Around a portion of the circumference of the rotating cylinder is wrapped a flexibly imaging medium such as photographic film (14), to which is applied longitudinal tension through means of a film transport (10). The film conforms to the curvature of the drum, but is held a small distance above the surface of the cylinder in equilibrium between the aerodynamic forces created by the rotating cylinder and the applied tension of the film transport, thus effecting a compliant surface air bearing. A scanning beam is used to write on the film in the line direction. Longitudinal movement of the film is used to affect scanning in the page direction.
