Abstract
A method of selectively illuminating a surface, such as a light-sensitive recording medium or an information record, provides a slit traveling transversely to a longitudinal dimension thereof and images light from a source of spatially concentrated light through the slit onto the above mentioned surface anamorphically only as to a dimension of the spatially concentrated light corresponding to the longitudinal dimension of the slit. Light is further spread from the source in a plane parallel to the transverse travel of the slit and is collimated, to be projected through the slit onto the above mentioned surface and for the extent of at least a portion of the transverse travel of the slit.
