Abstract
A system (21) is proposed for transferring data to plate-like data carriers (23, 23'), the system comprising a holder (22, 22'), shaped at least partly as an inner cylinder, to arrange the data carriers (23, 23')--of which the side provided to accept data faces the cylinder axis (29) of the holder (30)--and a transfer head (30) which can rotate about this cylinder axis and has at least one transfer means (24)--for transferring the data to the data carrier (23, 23') the holder (22, 22') and the transfer head also being capable of moving relative to each other in the direction of the cylinder axis (29) and the distance between at least one surface of the transfer head (30) or transfer means (24) and the data carrier--during the transfer of data--preferably being less than 1/4 of the holder diameter and particularly preferably less than 1 cm. The system (21) is characterized in that the transfer means (24) comprises an array of 24 to 256 light sources for transferring the data using a multi-beam technique; according to a first embodiment, the transfer head is arranged both such that it can move in the direction of the cylinder axis of the holder and can rotate about the cylinder axis …
