A pulse generator generates a recording pulse signal based on a preset data signal to drive the radiation source, wherein the recording pulse signal comprises a cooling pulse, and wherein the preset data signal corresponds to a mark and space of equal length and is recorded onto the rewritable optical disc in terms of a written mark and space. A pulse controller determines a final width for the cooling pulse according to a difference between lengths of the written mark and the written space.
