Record carrier of the optical type and a device for recording and/or playback for use with such a record carrier

The invention relates to a record carrier of a disc-like optically inscribable type, having a preformed track in which an auxiliarily signal comprising a sequence of codes is recorded by means of a preformed track modulation. The codes comprise a sequence of address codes (AC) specifying the addresses of the track portions in which said address codes (AC) are recorded and special codes (SC). The special codes (SC) can be distinguished from said address codes (AC) and specify control data for controlling a recording by a recording device. The record carrier is provided with an extended area (XAA) proceeding a program calibration area (PCA), the extended area (XAA) comprising special codes (SC) representing additional control information for controlling a recording.
