ABSTRACT:
Recording apparatus for recording in a track on an optical information carrier a first channel signal representing a main information signal, a second channel signal representing a cue information signal and a third channel signal representing a sub information signal. The main information signal includes at least one programme item and the cue information signal includes for the at least one programme item an indication of its location on the track. The recording apparatus includes a unit for receiving the main information signal, the cue information signal and the sub information signal; a unit for encoding the main information signal providing the first channel signal; a unit for encoding the cue information signal, providing the second channel signal; a unit for encoding the sub information signal, providing the third channel signal carrying sub information packs in substantially non-interleaved form, by generating sub information packs, including data from the sub information signal plus data for error detection and correction thereof, in substantially non-interleaved form; and a unit for writing the first channel signal in a main information area of the track on the information carrier and for writing the second channel signal and the third channel signal in a lead-in area of the track preceding the main information area.
