摘要： The present invention relates to a method and a corresponding device for transforming a first set of write parameters (W) of a write strategy, in particular a 2T write strategy, for recording marks in an information layer (301) of a record carrier (30) by irradiating the information layer (301) with a pulsed radiation beam (32) at a first recording speed (R) into a second set of write parameters (W′) of said write strategy for recording marks at a second recording speed (R′), T representing the length of one period of a reference clock. In order to achieve an at least acceptable recording performance at the second recording speed, it is proposed according to the present invention that the duration of the write pulses is kept substantially constant in time, and the duration of a complete sequence of write pulses for recording a mark is kept substantially constant as a fraction of the reference clock T.

摘要： The present invention relates to a recording apparatus and a corresponding method for recording information in an information layer of a record carrier (10) by irradiating the information layer (101) by means of a radiation beam (12), said information layer (101) having a phase reversibly changeable between a crystalline phase and an amorphous phase. In order to ensure that previously written marks are completely erased, irrespective of the mark width which may be the result of a different writer used for recording such a previously written marks, a recording apparatus is proposed comprising: —a radiation source (11) for emitting said radiation beam for writing, erasing and/or reading information, —a control unit (15) operative for controlling the power of said radiation beam, —a detection unit (16) for detecting previously written marks in said information layer and for determining the mark widths of previously written marks, wherein said control unit (15) is adapted for controlling write parameters for writing information based on the mark width of previously written marks.

摘要： A method for setting an optimum value of a write power level for use in an optical recording apparatus for writing information on a recording layer (3) of an optical recording medium (1) by means of a radiation beam (5) is described. The recording layer is able to change between an amorphous and a crystalline state. The apparatus comprises a radiation source (4) for emitting the radiation beam (5) having a controllable value of a write power level (Pw) for recording information on the recording medium, a control unit (12) for recording a series of test patterns in a test area on the recording layer, each pattern being recorded with a different value of the write power level, a read unit (90) for reading the patterns and forming corresponding read signal portions, and first means (10, 101, 102) for deriving a value of a read parameter from at least one read signal portion and setting an optimum value (Popt) of the write power level based on the values of this read parameter. According to the invention the apparatus further comprises second means to perform at least one initial step (40) of at least partly amorphizing and subsequently recrystallizing the recording layer. In this way a consistent result for the determined optimum value (Popt) of the write power level (Pw) is obtained.
