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.
