ABSTRACT:
Apparatus for marking a bitmap image on tape includes a source of a modulatable laser-beam. The beam is directed to an oscillating mirror on a carriage translatable across the width direction of the tape. The oscillating mirror directs the beam to a focusing lens mounted on the carriage. The focusing lens is arranged to focus the beam to a focal-spot on the tape. As the carriage is translated, the focal-spot is swept reciprocally in a wave-like path across the tape. Modulation of the beam is arranged such that pixels of a plurality of rows of the bitmap image are printed in one traverse of the carriage. The tape is advanced incrementally and repeated traverses of the carriage are made to complete printing of the bitmap image.
