ABSTRACT:
The invention relates to a device, a method and a corresponding computer program product for transmitting data to a carrier. The device (1) comprises a control system (2), a holding surface (3) which is used to hold the carrier (4) and a transmission head (5) for transmitting data from a data memory (6) to said carrier (4). The holding surface (3) is arranged in such a way that it can be rotated about an x-axis (8) by means of a first drive device (7) and the transmission head (5) is arranged in such a way that it can be moved along a y-axis (10) by means of a second drive device (9). Both the holding surface and the transmission surface are controlled by the control system (2) in a coordinated manner. The invention is characterized in that the device (1) comprises an additional computer (16) in which a computer program product can be installed, said computer program product comprising software code segments with which, when this computer program product is running on said additional computer (16) and by means of generating polar co-ordinates, data is read out of, in a circular manner, a linear file read into or stored in the working memory (RAM) of the computer (16). The data determined in this way is allocated via the memory store (6) to the transmission head (5) for transmission to the carrier (4).
