<p>An information recording device (Fig. 1) is disclosed, which device comprises write means (3, 8) for providing the record carrier (1) with information patterns (58, 59). The write means (3, 8) are adjustable. In determining the optimum adjustment a calibration procedure is carried out. For different settings of the write means (3, 8) information patterns (58, 59) are recorded. The optimum setting is determined on the basis of the recorded information patterns. The information recording device further comprises storage means for storing in a memory the determined optimum setting together with identification data which indicate for which combination of the recording device and a record carrier (1) the adjustment data has been determined. After a record carrier (1) has been loaded into the information recording device, it is detected whether adjustment data for the relevant combination of a record carrier (1) and an information recording device has been stored in the memory (1, 12). If adjustment data for said combination has been stored the write means (3, 8) are adjusted in conformity with this data and no new calibration procedure is performed, which saves a substantial amount of time.</p> |
