Abstract
An apparatus generates outgoing data (OD) to be provided on an optical disk () in a burst cutting area (). The burst cutting area () further comprises markings () which cause a marking frequency spectrum (MFS) when reading out the burst cutting area (). The apparatus comprises a channel coder () which receives processed data (PD) and supplies the outgoing data (OD) having an outgoing data frequency spectrum (DFS) with suppressed DC-content. The apparatus further comprises a data processing device () which generates the processed data (PD) to obtain an outgoing frequency spectrum (DFS) wherein a frequency component causing interference with a low frequent component of the markings () is suppressed or not present.
