    摘要: A video signal recording system and method for recording a video signal including a luminance signal (Y), a first color signal (P B ) and a second color signal (P R ) in a plurality of mutually obliquely parallel tracks on a magnetic tape (30). In the system and method, at least two heads (28, 29, 28a, 28b, 29a, 29b) having different azimuth angles forms the plurality of tracks. The luminance signal (Y) and the first color signal (P B ) are processed and then applied to one (28, 28a, 28b) of at least the two heads (28, 29, 28a, 28b, 29a, 29b) having a predetermined azimuth angle to record a signal based on the luminance signal (Y) and the first color signal (P B ) in the tracks formed by the head (28, 28a, 28b) having the predetermined azimuth angle. The luminance signal (Y) and the second color signal (P R ) are processed and then applied to the other (29, 29a, 29b) of at least the two heads (28, 29, 28a, 28b, 29a, 29b) having another azimuth angle different from the predetermined azimuth angles to record a signal based on the luminance signal (Y) and the second color signal (P R ) in the tracks formed by the other head (29, 29a, 29b) having the other predetermined azimuth angle.
