Abstract
The present invention overcomes the wear and tear problems caused by prior art methods by placing the digital information in the space reserved for analog soundtrack information, which traditionally is not touched by transport rollers or pressure plates. This invention describes a method by which digital information is simultaneously recorded with the analog track in the same area occupied by the present analog track by utilizing the techniques of spectral processing and digital bit manipulation. Thus, maximum separation and minimal interference can be achieved between the digital and analog tracks.
