Abstract
In a video recorder having a drum with opposing dual record heads, successive fields of only the luminance signal (without the chrominance signal) are recorded by the heads during successive head rotations through 180.degree.. The tape is overwrapped around the drum by a certain angle (over 216.degree., for example) so that the chrominance signal of each preceeding field may be compressed and recorded during each head rotation through the overwrap angle (i.e., from 180.degree. to 216.degree. in the example). Because the luminance signal is not mixed with the chrominance for recording (as has been usual), the luminance bandwidth may be increased by about 1 megaHertz to occupy the frequency band otherwise occupied by the color-under chrominance signal in the prior art. This provides a significant improvement in overall video image resolution.
