ABSTRACT:
An apparatuses for preventing magnetic recording errors in an advanced photo system camera. The apparatus comprises a film transport sensing unit for detecting a perforation in a film and for generating an output signal for each detected perforation. A control unit determines whether noise has occurred in the transport sensing unit output signal while the film is being advanced. When noise occurs in the transport sensing unit output signal, the control unit prevents recording of photographic data on the film for a predetermined period of time. The apparatus also includes a magnetic recording unit for magnetically recording the photographic data on the film according to a control signal output by the control unit.
