发明名称 Methods and devices for recording marks on a recording surface of an optical record carrier
摘要 The invention relates to methods and devices for forming marks and lands by applying a radiation beam (32) to a recording surface (301) of an optical record carrier (30). Recording strategies are proposed for recording information at high recording speeds. An intermediate power level (P1, P2) is introduced in between the bottom power level (P0) and the write power level (Pw) , its value being dependent on the length of the preceding land (151, 152, 153). A raised write power level (PR1, PR2) is also proposed, its value being dependent on the length of the mark to be recorded (241, 242, 243).
