Abstract:
System for transferring data to plate-like data carriers, the system comprising: a holder, shaped at least partly as an inner cylinder, to arrange the data carriers with the side provided to accept data facing the cylinder axis of the holder, and a transfer head which can rotate about this cylinder axis and has at least one transfer means, for transferring the data to the data carrier; the holder and the transfer head also being capable of moving relative to each other in the direction of the cylinder axis, and a distance (d) between at least one surface of the transfer head or the transfer means and the data carrier, during the transfer of data, being less than 1/4 of the holder diameter; and wherein the transfer means is constantly rotating during the transfer of data and comprises an array of 24 to 256 light sources for transferring the data using a multi-beam technique, the array is equipped with one common optical means for imaging the array of light sources onto the data carrier the distance (d) is less than 1 cm and the transfer head or the transfer means is radially displaceable for the adjustment of the image-setting distance (d).
