Abstract: A photographic still provided with a magnetizable coating is inserted into a recording/playback device provided with a movably mounted head unit having a set of heads. A rotary motor drives an endless belt in a single direction, the upper and lower runs of the belt always travelling in opposite directions. The head unit is alternately coupled to the upper and to the lower run of the belt, for travel in one and then the opposite direction. Upon each reversal of the travel direction of the head unit, a successive one of the magnetic heads is activated, so as to track a meandering track on the magnetic coating.

Abstract: An accessory unit, for example an electronic flash unit, for use with photographic apparatus has a housing provided with one or more connecting elements for detachably connecting the unit to the apparatus. The housing has a through-going, essentially slot-shaped passage through which self-developing film sheets ejected from the apparatus can pass, or through which a strap or other retaining element of the camera can extend which holds the unit adjacent to the camera even when the unit is not in operative position, i.e. when the unit is detached from the photographic apparatus.
