Imaging apparatus is provided which includes a generally cylindrical drum defining a substrate support surface, a head operative to record information onto a substrate on the substrate support surface, and substrate feed and position apparatus for precise rotational positioning and displacement of the substrate with respect to an internal surface of cylindrical drum. The apparatus includes a plurality of linear motors arranged along the internal surface of the cylindrical drum for feeding the substrate, and control apparatus for controlling the linear motors to achieve precise positioning of the substrate support surface.
