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.

摘要： In an optical record carrier recording method for forming marks and lands by irradiating a radiation beam onto a recording surface of an optical record carrier, the radiation beam for each mark to be recorded is set to at least one write power level (Pw) capable of forming a mark during a mark period (31) and, for each land between the marks, to at least one bottom power level (P0) incapable of forming a mark during a land period (32). When recording a wobble signal on the record carrier, in order to achieve a better wobble signal-to-noise ratio during writing, the bottom power level (P0) is temporarily raised to an intermediate power level (Pi) during an intermediate period (34). Preferably, the intermediate power level (Pi) is set within a range of from 1.5 to 6, in particular, from 2 to 4, times the bottom power level (P0).

摘要： A rewritable data storage medium has a rewritable recording layer provided with a tracking structure. The recording layer has a data recording area. An erasable identification mark is present in an identification mark area other than the data recording area. The data recording area has a first tracking structure, whereas the identification mark area is substantially free from a tracking structure or has a second tracking structure substantially different from the first tracking structure, such as including concentric or interrupted spiral grooves. Thus erasure of the identification mark is practically impossible, because the location of the erasing spot of a recorder cannot be controlled precisely in radial direction in the identification mark area.
