Title: Method of recording a digital information signal on a record carrier, record carrier provided with such an information signal, and read/write apparatus for such a record carrier.
IPC: G11B5/58
Filed: 1984-03-02
Abstract: For a controlled positioning of a read element relative to a track to be read during the read-out of such a record carrier, low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, these tracking signals are represented by the d.c. content of the information signal. During conversion of the information words of the information signal into channel words steps are therefore taken to provide two channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depending on a control signal which depends on the desired tracking signal.
