Abstract
A photographic camera is provided with magnetic recording means including a frequency selection circuit responsive to a controller to iteratively record data on a magnetic recording layer formed on photographic film with each iteration being recorded at a different recording frequency. Suitable selection of recording frequencies for a range of expected film speeds will result in a predetermined number of recorded iterations for which respective bit densities and cumulative recorded track length will fall within predetermined acceptable limits established for reliable reading of the data by subsequent data read circuits.
