ABSTRACT:
A method and apparatus for improving the image quality of a CRT recorder wherein image information is transmitted to the image receiving medium through a plurality of tracks provided on a phosphor stripe of the CRT. An algorithm in the memory determines the deflection of the electron beam so that the tracks are activated in a predetermined order. As the image receiving medium is scrolled past the CRT faceplate, the image will be exposed on the image receiving medium so that no two adjacent image lines are exposed by adjacent tracks. In a further embodiment, image lines are produced by activating the tracks in a random order.
