ABSTRACT:
Radiation scanning apparatus comprises a record medium support (10); and a rotatably mounted scanning device (1) on which a modulated radiation beam (6) is incident in use. The device splits the incident beam into at least two subsidiary beams (17,21) which scan in turn across a record medium on the support during relative rotation between the scanning device and the support, each subsidiary beam exposing a respective scan line on the record medium in accordance with the beam modulation. The support (10) and device (1) are relatively movable such that the scan lines are offset in the direction of relative movement.
