Abstract
A record carrier, a recording device and method, and an information recording system including the recording device and the record carrier. The record carrier has a track which is transversely modulated in accordance with an auxiliary signal. The auxiliary signal includes address codes which specify addresses at which those codes are located on the track, and auxiliary codes which specify control data. The recording device and method are adapted to read the auxiliary signal from the record carrier, and use the control data when recording information on the record carrier. The address codes and auxiliary codes are distinguishable from each other and can be extracted from the auxiliary signal by the recording device and in the recording method.
