ABSTRACT:
A camera, capable of loading a cartridge housing a film which is provided with image recording areas and a magnetic recording area in which plural sets of a same magnetically recorded information are consecutively recorded along the longitudinal direction, is provided with a film feeding device for effecting a pre-winding operation for winding the film in the loaded cartridge to the end onto a winding spool prior to the photo-taking operations; a magnetic head capable of being contacted with or separated from the magnetic recording area of the film and reading the magnetically recorded information in the contacted state; a contact/separating mechanism for contacting or separating the magnetic head with or from the magnetic recording area of the film; and controller for controlling the contact/separating mechanism so as to contact the magnetic head with the magnetic recording area, in the course of the pre-winding operation, for a period which is shorter than the time required from the start to the end of the pre-winding operation but is enough for reading at least a set of the magnetically recorded information.
