| 摘要 |
The present invention relates to a recording apparatus, a record carrier, and a method of controlling a radiation power used for recording data on a record carrier, wherein a write power control is performed on the basis of temperature and disc-dependent parameters to solve write performance problems, especially on dye media. To achieve this, a first control parameter indicating a variation of the radiation power due to a non-homogeneity of the record carrier is predicted as a function of a recording position, and a second control parameter indicating a temperature dependency of the radiation power is predicted based on a measured temperature. Thereby, accuracy of writing power control can be improved, especially in case of a jump between arbitrary recording positions. |
