摘要:
The present invention relates to a recording apparatus, record carrier and method of recording data on at least two layers of a recording medium by using a radiation power, wherein individual recording speeds are determined for respective ones of the at least two layers at different values of the radiation power. A recording speed to be used for recording on an individual one of the at least two recording layers is selected based on a maximum radiation power specified for the recording operation, and the speed of the recording operation is controlled individually for each of the at least two layers based on the selected recording speed. The determination of the individual recording speeds at different radiation power values may be written or embossed on the record carrier. Furthermore, a recording sequence used for recording on the recording layers can be set based on the sensitivities and thus recording speeds. Thereby, total recording time can be minimized for multi-layer recording media.
摘要:
A writable optical record carrier comprising a plurality of recording layers L0, . . . , Ln−1 separated by a spacer material, each recording layer comprising an optimum power calibration area having a first portion with an average reflection value representative of a recorded layer and a second portion with an average reflection value representative of an unrecorded layer, a method, and an apparatus for forming optimum power calibration areas on such a writable optical record carrier are presented. The optimum power calibration areas partially overlap such that the optimum power calibration areas of each pair of consecutive recording layers form a step, and the first portions of said plurality of recording layers have the form of a staircase. Each step formed by a pair of consecutive recording layers k, k+1 has a preferred minimum step size.

摘要:
This invention relates to a method for recording information on a multi layer record carrier. The information is recorded on the record carrier according to special filling patterns, such that the record carrier is compatible with the DVD-ROM standard while the time required for closing a session and/or finalizing the disc is reduced. The information is substantially evenly distributed over the layers in blocks of a predefined amount of storage space. The size of these blocks may be flexible and set by the method or read from the record carrier.

摘要:
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.
