ABSTRACT:
Facsimile recording on a video disc, wherein a document such as a bank check is recorded as a frame of video information, generally requires that the frame of recorded information be displayed or transformed into a hard copy reproduction of the original document. In accordance with a presently preferred embodiment of the invention, the frame of video information is recorded on a video disc as two fields of interlaced lines recorded on adjacent circular tracks. Upon playback, the circular tracks are alternately read to produce the customary video display of two interlaced fields. To provide a hard copy reproduction of the original document, the circular tracks are simultaneously read and the resultant signal fed to a signal processing circuit. The output of the signal processing circuit comprises, in alternation, lines of video information from each field. This output signal is fed to a printer device which prints, line-by-line, a hard copy reproduction of the original document.
