ABSTRACT:
A process and an apparatus are specified for recording a digital signal onto a recording carrier (4), in particular a signal for recording in compact disc data format, in which an engraving or cutting stylus (2) is pressed substantially by dead weight alone against the recording carrier (4) and, in operating mode, describes a path which lies beneath the undeformed surface of the recording carrier (4) during an indentation to be engraved and on or above the undistorted surface of the recording carrier (4) between two indentations, the common center of gravity position of the engraving stylus (2) and positioning element (1) connected rigidly to it remaining substantially stable in position.
