Abstract
Abstract A camera has a recording apparatus for magnetically recording finished photograph information, indicating exposure of a film frame, and for magnetically recording other photograph information for each film frame. The finished photograph information is recorded at a designated film area, while a film feed motor is in a transient speed state. Other photograph information is recorded in a designated film area when the film feed motor speed is constant. Appropriate positioning of the designated recording areas for recording information therein is determined by counting film perforations or by measuring a period of time during film feed subsequent to an exposure.
