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.
