ABSTRACT:
The invention relates to a method and a device for recording an information signal10in a phase change layer of a recording medium. A mark is recorded by a sequence13of write pulses and previous marks between the marks to be recorded are erased by a sequence of erase pulses14. De bias power level191, 192between the erase pulses is made dependent on the recording speed, thus obtaining low jitter of the recorded marks and at the same time preventing thermal cross write during erase.
