Abstract
A recording head arrangement is disclosed which may be employed in a video signal recording and/or reproducing device in which a video tape is helically wound on a drum carrying recording heads for recording and/or reproducing a video signal. The video signal is divided for representing upper and lower half images on a screen. The recording head arrangement includes first and second heads mounted on the drum adjacent each other. The first and second heads have the same azimuth angle which is inclined in a first direction with respect to a direction perpendicular to the head advancing direction. Third and fourth heads are mounted on the drum 180 degrees spaced from the first and second heads, respectively. The third and fourth heads have the same azimuth angle which is inclined in a second direction, opposite to the first direction. The first and second heads are scanned to form first and second tracks spaced apart by approximately one track width for recording and/or reproducing the first half image, and the third and fourth heads are scanned to form third and fourth tracks spaced apart by approximately one track width and in an interlaced manner with the first and second tracks for recording and/or reproducing the second half image.
