Abstract

A method for writing an optical record carrier, in which a mark representing recorded data is written in the record carrier by a sequence of radiation pulses. The radiation power has a different level in between the pulses of a sequence and immediately after the last pulses of a sequence. This allows an independent control of the leading and trailing edge jitter of the marks written.
