ABSTRACT:
In the disclosed motion picture projector the original sound recorded on the main magnetic stripe along one edge of a film stripe also having a magnetic balance stripe along the other edge of the same film surface, is reproduced by a recording-reproducing head. A second recording-reproducing head records the signal on the balance stripe. While the original sound signal is being heard, the first recording-reproducing head overlaps a second sound signal on the main stripe. A part of the original sound signal on the main stripe may be erased and a new signal recorded in its place.
