I dunno, it looks more like the drum sets the H rate, and the spiral cuts in the disc set the V rate. The drum and disc are locked together arithmetically by the gearing, and the camera would need to have an identical mechanism. It wouldn't be compatible with any other scanning format. Seems like, anyhow.
Wonder if this format originally used a flying-spot scanner rather than a "camera".
