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.
