Abstract
Apparatus for laser-marking on tape includes a laser arranged to emit a modulated beam of laser-radiation. Projection-optics are arranged to focus a beam to a spot on the tape. The tape is driven under the focal spot for scanning the beam in the length direction of the tape. The projection-optics are rotated reciprocally to scan the focal spot over the tape in a direction transverse to the length direction of the tape.
