ABSTRACT:
A digital video signal recording and reproducing apparatus which obtains a favorable reproduced picture even when the data overwritten by edited data is interpolated with the data of the preceding field or preceding frame by recording the video data of the visually inconspicuous peripheral area on a track that is possibly overwritten by the editing data at a cut-in point or cut-out point in assemble editing or insert editing. The apparatus further obtains a natural picture without any fixed error even in speed search mode by exchanging the recording order of the video data of one field on plural tracks according to the head scanning trace in the speed search.
