Data recording device for motion picture film.

摘要

A data recording device for a motion picture film is provided in which plural optical fibers (2) are connected to light emitting devices (3) at one end and the other ends of the optical fibers are arrayed in accordance with a dot pattern of audio data to be recorded. The light emitting diodes are turned on responsive to the audio data to be recorded on the motion picture film. The audio data carrying light, produced by turning on the LEDs, is conducted via the optical fibers to a head unit (1) so as to be radiated on the motion picture film via a radiating port of the head unit. By the above arrangement, the optical fibers may be arrayed optionally at the head unit without regard to the arrangement of the LEDs. Consequently, the LEDs can be arranged to avoid overheating problems. By linearly arraying the optical fibers at the head unit (1), a large quantity of audio data may be recorded on the motion picture film.
