Abstract
A method and camera apparatus for magnetically recording data on a photographic film magnetic layer in dual parallel data tracks wherein a first data track is recorded as the film is transported in one direction and a second data track is recorded as the film is transported in the reverse direction. In this manner, recording is simplified since only one recording track of a recording head is needed for recording in the dual data tracks and memory requirements are minimized by recording high content data as each frame is exposed, leaving the low content data to be stored in memory for recording during rewind of film into the cassette.
