<p>Methods and devices 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 rear heating pulse (24) is introduced after a last write pulse (23, 26) and a front heating pulse (25) is introduced before the first write pulse (22,26). The power level (13) of the front heating pulse and the power level (15) of the rear heating pulse may be dependent on the length of the mark to be recorded and on properties of the record carrier. The method results in a reduced jitter of the marks written, especially when writing at high recording speeds.</p> |
