METHOD AND DEVICE FOR RECORDING AN INFORMATION SIGNAL ON AN INFORMATION LAYER OF A RECORDING MEDIUM

摘要

The invention relates to a method and a device for recording an information signal (10) in a phase change layer of a recording medium. A mark is recorde d by a sequence (13) of write pulses and previous marks between the marks to b e recorded are erased by a sequence of erase pulses (14). The bias power level (191) between the erase pulses is made dependent on the recording speed, thu s obtaining low jitter of the recorded marks and at the same time preventing thermal cross write during erase.
