Abstract
The invention relates to a method and a device for recording an information signalin a phase change layer of a recording medium. A mark is recorded by a sequenceof write pulses and previous marks between the marks to be recorded are erased by a sequence of erase pulses. De bias power levelbetween 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.

Method and device for recording an information signal on an information layer of a recording medium in which a bias power level of the radiation beam varies with the recording speed during erase pulses (U.S. Patent No. 7359297).
