Abstract
Abstract Imaging apparatus is provided which includes a generally cylindrical support defining a substrate support surface, a head operative to record information onto a substrate on the substrate support surfaces, and apparatus for precise rotational positioning and displacement of the cylindrical drum with respect to the imaging head. The apparatus includes at least one linear motor arranged to drive the cylindrical support in rotational motion, and control apparatus for providing electrical inputs to the linear motor to achieve precise rotational positioning of the substrate support surface.
