ABSTRACT:
The invention relates to recording of information, in particular a real-time audio and/or video signal, in a recording track (3) of a recording medium (2) divided into blocks (45). The recording medium contains a defect list (BS) of addresses of blocks (45*) which are known to be defective. This list is read and during the recording process the defective blocks are skipped. The recording process is performed without any read-after-write check so as to speed up the process. The defect list is updated by noting, during playback, which blocks give rise to reading problems and by including the addresses of these blocks in the defect list on the recording medium.
