ABSTRACT:
A signal recording and/or reproducing apparatus, such as a video tape recorder or the like, records and/or reproduces an information signal indicating a date of recording, a video signal and a PCM signal from a helical track on a record medium, such as a magnetic tape. The track has first and second portions which respectively record the PCM signal and the video signal. In certain advantageous embodiments, the information signal is recorded in a guard band area between the first and second portions of the track. The apparatus has the capability of selectively superimposing the date information on the video signal for display. A record medium in which a plurality of such helical tracks are formed may be searched to locate signals recorded on a selected date, thus providing a convenient search capability which is implemented in a simple and straightforward manner.
