Abstract
A recording apparatus records data on a sensitive material with a laser beam. The recording apparatus includes a data storage unit for storing data, a laser illumination unit for generating the laser beam, and a laser beam scanning unit for scanning the laser beam, which is generated by the laser illumination unit, at a predetermined position. The recording apparatus further includes a transporting unit for transporting the sensitive material to the predetermined position, a laser control unit for controlling the laser illumination unit to generate the laser beam on the basis of the data stored in the data storage unit, and an intensity change-over unit for changing over the intensity of the laser beam illuminating the sensitive material at the predetermined position, in dependence on the type of the sensitive material.
