A recording device for recording data on a rewritable optical record carrier (11). The device comprises recording means (21, 22, 25) for forming marks on the record carrier during recording operations by irradiating the record carrier with a radiation beam (24), the marks representing the data. Further, the device comprises control means (20) for controlling the recording operations and beam control means (31) for controlling a write power of the radiation beam with reference to an optimum write power by changing the write power within a predetermined write power range around the optimum write power for subsequent write cycles, each of the write cycles comprising at least one recording operation. Variation of the write power improves the overwrite quality, in particular, in the management area, such as the file system area. |
