Method and device for recording marks in an information layer of an optical record carrier |
摘要 |
A method and device are described for writing an optical record carrier, in which a mark representing recorded data is written in a phase change layer of a record carrier by a sequence of radiation pulses. A trailing power level (t) having a value higher than the erase power level (e) is introduced after a last write pulse 3 in a sequence. Additionally, the power level of the last write pulse 3 in a sequence may be raised. This results in a reduced jitter of the marks written, especially when writing at high recording speeds. |
