摘要 |
A record carrier has substantially parallel tracks, which exhibit first variations of a first physical parameter and second variations of a second physical parameter of the track. The first variations represent information recorded on the record carrier, which information is recoverable by means of a controllable type of data processing. A modulation pattern of the second variations represents a code for controlling said type of data processing. The record carrier has a limited area (S1,S4) in which the tracks have the second variations, the further tracks having no second variations. The device comprises a control unit for locating the limited area (S1,S4) for retrieving the code from the modulation pattern of the second variations of the tracks in the limited area. <IMAGE>A record carrier has substantially parallel tracks, which exhibit first variations of a first physical parameter and second variations of a second physical parameter of the track.
