Abstract
A camera includes a feeder for feeding a film having magnetic recording portions, a reader for magnetically scanning magnetic recording portions to generate scan signals, and a judger for judging whether or not a magnetic recording portion has been recorded with magnetic data by comparing scan signals with a threshold value, and a warning device for generating a warning when judgment of the judger is impossible. This apparatus can ensure more accurate judgment as to whether a signal picked up from each recording portion is a magnetic signal.
