Abstract
A data recording apparatus for a motion picture film for digitally recording data concerning an image of the motion picture film. The data recording apparatus includes a plurality of light emission units (LEDs) 4 lighted responsive to the data concerning an image, a light volume detection units 5 for detecting the light emission volume of each of the light emission unit, a reference value outputting unit 6 for outputting a reference output specifying a reference value of the light emission volume of the light emission unit and a control unit 8 for comparing the reference output value of the reference value outputting unit 6 to each detected output value from the light volume detection unit 5 for controlling the light emission of the LEDs 4 so that each detected output value will be equal to the reference output value. With the data recording apparatus for a motion picture film, each light emitting unit operates with the uniform light emission volume during data recording, thus enabling printing fluctuations of the recording pattern of the negative motion picture film for improving the SN ratio at the time of reproducing a positive film obtained from the negative film. Specifically, the negative film can be improved in quality inexpensively during recording of digital audio data on the motion picture film.
