Support recording, playback device and method of recording information.

Record carrier comprising substantially parallel tracks - exhibiting first variations of a first physical parameter of the track, representing the first variations information recorded on the record carrier, and - exhibiting second variations of a second physical parameter of the track, - in which, in connection with a track (42) showing said second variations, a modulation pattern of the second variations of the second physical parameter of the track (41) adjacent the left is aligned with a modulation pattern of the second variations of the second physical parameter of the track (43) adjacent to the right of the recording medium, wherein the information represented by the first variations can be recovered by means of a controllable type of data processing, a modulation pattern of the second variations a code track represents a code for controlling said type of pr ocesamiento data, and laspistas mentioned exhibiting the second variations are separated from each other by intermediate areas not constituting tracks.
