Video tape recorder with particular format chrominance and luminance information

Claim 1

A video tape recorder for recording on a magnetic tape a video signal composed of a first signal having luminance signal information and a second signal having chrominance signal information, which comprises: means for exchanging said first signal and said second signal every predetermined period L to obtain two combined signals each composed of said first signal and said second signal which occur alternately at intervals of L; means having two pairs of rotary magnetic heads for recording said two combined signals on a magnetic tape so as to form signal tracks with no spaces between each adjacent two of said signal tracks, two heads of each of said pairs being disposed to be apart by a predetermined distance S in a rotating direction of said heads; and means for moving said magnetic tape so that a signal track of one field is shifted from a signal track of next field by a predetermined distance α, wherein said period L, said distance S and said distance α are selected as follows: L=kH; S=(2n-1)L; and α=(i/2)L, where H denotes a horizontal scanning period and each of k, n and i denotes an arbitrary integer, whereby said first signal and said second signal recorded on each signal track are respectively adjacent to said first signal and said second signal recorded on each adjacent signal track which is adjacent to said each signal track.
