The present invention relates to a recording device (1) and a corresponding recording method for recording user data in a user area (UA) on a recordable or rewritable optical record carrier (4) comprising OPC means (3) for performing optical power calibration by writing OPC test data on a record carrier (4) before user data are recorded thereon. To avoid the problem that no more user data can be recorded on the record carrier since an OPC area (40) particularly reserved for writing said OPC test data is full, and to enable the provision of a smaller OPC area (40), it is proposed according to the present invention that the OPC test data are written in said user area (41, 42) if the OPC area (40) reserved for writing said OPC test data is not usable or not provided on the record carrier (4).
Recording device (1) for recording user data in a user area (UA) on a recordable or rewritable optical record carrier (4), said recording device comprising OPC means (3) for performing an optimum power calibration procedure by writing OPC test data on the record carrier (4), said OPC means (3) being adapted for writing said OPC test data in said user area (UA;
Recording method for recording user data in a user area (UA) on a recordable or rewritable optical record carrier (4), comprising the step of performing an optimum power calibration procedure by writing OPC test data on the record carrier (4), wherein said OPC test data are written in said user area (UA;
Record carrier (4) on which user data can be recorded in a user area (UA), said record carrier storing OPC test data written on the record carrier (4) in said user area (41, 42) for performing an optimum power calibration procedure.
