Abstract

Abstract A method of recording information relating to an image photographed on a photographic film in which the photographic film comprises a magnetic track associated with each image frame for magnetically recording the information. Each magnetic track has two or more fields. The information is divided into sections which are each recorded onto any of the fields together with a start signal, an end signal, and an error detection and/or correction signal for each the information section. Consequently, even if the information to be recorded for each image frame is interrupted due to an error in the conveying speed of the film, a portion of the information can be read and utilized.
