ABSTRACT:
A camera of the kind having a magnetic head for magnetically recording data in a track part of each frame portion of a film is arranged such that, in re-recording information in the track part having a previous record of data, a predetermined signal for erasing information is supplied to the head during a period other than a period during which a data signal is supplied to the head, so that new data can be recorded by completely erasing, without fail, the previous record of data in carrying out the re-recording.
