Abstract:
A method of selectively recording a video signal of L different video signals respectively having first to L amounts of video data per frame or field and a sound signal accompanying said one video signal on a magnetic tape using a helical scanning head unit, L being a natural number greater than 1, the method comprising the steps of:(a) sectioning said one video signal and said sound signal every Mk frames or fields, said Mk being a natural number greater than one and determined by dividing a common multiple of said first to L amounts of said video data of said video signals per frame or field by the amount of video data per frame or field of said one video signal; and(b) recording said sectioned video signal and said sound signal on said magnetic tape such that said Mk frames or fields are recorded on one unit of T tracks on said magnetic tape with a common track pattern being repeated along the magnetic tape, T being a natural number greater than one.
