ABSTRACT:
A data recording device for a motion picture film is provided in which one ends of plural optical fibers are connected to light emitting devices 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 the turning on of the LEDs, is conducted via the optical fibers to a head unit 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 array of the LEDs. Consequently, the LEDs are affected to a lesser extent by heat evolved on turning on the LEDs. By linearly arraying the optical fibers at the head unit 1, a larger quantity of audio data may be recorded on the motion picture film.
