Detection of data in burst cutting areas of optical disk

摘要

An apparatus generates outgoing data (OD) to be provided on an optical disk ( 1 ) in a burst cutting area ( 2 ). The burst cutting area ( 2 ) further comprises markings ( 3 ) which cause a marking frequency spectrum (MFS) when reading out the burst cutting area ( 2 ). The apparatus comprises a channel coder ( 4 ) 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 ( 5 ) 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 ( 3 ) is suppressed or not present.
