ABSTRACT:
A photographic film processing apparatus has a data reader for reading magnetic data stored in a row of magnetic recorded tracks on a photographic film. The apparatus determines whether a reading error has occurred during film processing. If no error has occurred, then the film is processed in accordance with the magnetic data from the film. If an error has occurred, then the apparatus determines whether the data is eligible for replacement with reference data. If the erroneous data is eligible, then the film is processed in accordance with the reference data. If the erroneous data is not eligible, then the film is processed in accordance with external substitute data which is entered by an operator. Furthermore, the apparatus produces a maintenance demand signal based on the number of reading errors or the total length of photographic film processed.
