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