    Abstract: Test signals are recorded on a prescribed area in an optical disc. The prescribed area is scanned by a laser beam while the power of the laser beam is changed among different DC erasing values. The different DC erasing values are assigned to the recorded test signals, respectively. The recorded test signals are reproduced from the prescribed area to obtain reproduced signals. Parameter values of the respective reproduced signals are detected. The detected parameter values correspond to the different DC erasing values, respectively. Among the detected parameter values, a detected parameter value is decided which matches a target. One corresponding to the decided parameter value is selected from the different DC erasing values. A prescribed coefficient and the selected DC erasing value are multiplied to calculate an optimum level of an erasing power of the laser beam.

    Abstract: The present invention relates to a method of recording marks representing data in an information layer of a record carrier by irradiating the information layer by means of a pulsed radiation beam, each mark being written by a sequence of pulses, the recorded marks being erasable by irradiating the information layer with an erase radiation beam. In order to achieve a reduction of the temperature of a transparent heat sink of a dual-layer optical recording medium without compromising the direct overwrite of old data, it is proposed according to the present invention that said erase radiation beam has a first erase power level (e1) for a first erase period (t1), a second erase power level (e2) higher than or equal to said first erase power level (e1) for a second erase period (t2), and a third erase power level (e3) lower than said second erase power level (e2) for a third erase period (t3).

    Abstract: An optical disc recording method and apparatus is capable of overwriting a phase change optical disc at high speed. With a preceding erasing beam out of two laser beams, a modulation component in an RF signal recorded on an optical disc is erased to a state where no problem occurs (the reflectance difference is reduced) and the top level is decreased to 70 to 40% of a top level of an original RF signal. After that, with the subsequent recording beam, a space is recorded at a laser power at which top level is reset to the original state (before the erasing process), and a mark is recorded at a laser power which can sufficiently decrease the bottom level. Consequently, even when the recording speed is the quadruple speed (about 1.6 to 2 times of a specification) much higher than a specific recording speed (for example, 2 to 2.4×) of a phase change optical disc, overwriting can be performed with a recording characteristic which can satisfy a regenerating characteristic specification.

    Abstract: A multi-stack optical data storage medium (20) for rewritable recording using a focused radiation beam (30), entering through an entrance face (25) is described. The medium (20) has a substrate (1a, 1b) and an L0 recording stack (2) and an L1 recording stack (3) both comprising a phase-change type L0 and L1 recording layer and the recording stacks are separated by a transparent spacer layer (4). The L0 recording stack (2) is present at a position closest to the entrance face (25) and has an optical transmission of TL0a and TL0c when the phase-change layer respectively is in the amorphous phase and in the crystalline phase. The medium (20) contains pre-recorded information modulated in at least one of: an embossed pregroove (21) in the substrate (1a, 1b), embossed pits in the substrate and recorded phase-change marks in at least one of the recording layers L0 and L1 (6, 11). The pre-recorded information contains a flag whether formatting of the L0 recording layer of the L0 recording stack (2) is needed depending on the transmission values TL0a and TL0c of the L0 recording stack (2). In this way it is achieved that the medium (20) has a good playability, recordability and random access behavior even when the L0 recording layer (2) has been partially recorded with information.

    Abstract: An optimum power calibration method is provided and is implemented for writing a rewritable optical storage medium including a power calibration area. The method includes the steps of determining whether the power calibration area is recorded with data, erasing the entire power calibration area when the power calibration area is not recorded, and executing an optimum power calibration procedure. In addition, the optimum power calibration method is applied to a rewritable optical disk drive.
