    摘要: Current BD specification prescribes the following format for the ADIP: 24 bits, 3 of which to indicate the layer number, 19 for the RUB number, and 2 to be set to 00, 01 and 10 consecutively in the 3 successive ADIP words corresponding to one RUB that is the smallest partition of data that can be written on the disc. From this it derives that at most 32.2 GB of storage space can be addressed. Due to recent developments however, a storage capacity of 35 GB per layer could be achieved. A slight modification of the ADIP format is proposed, so as to allow an extension of the addressing space: the setting 11 for the two least significant bits is allowed, while the 19 bits no longer represent the RUB number. A drive will nevertheless convert the ADIP into a RUB number and vice versa, in a way which is transparent to a host device or application program.

    摘要: The present invention relates to a recording device (1) and a corresponding recording method for recording user data in a user area (UA) on a recordable or rewritable optical record carrier (4) comprising OPC means (3) for performing optical power calibration by writing OPC test data on a record carrier (4) before user data are recorded thereon. To avoid the problem that no more user data can be recorded on the record carrier since an OPC area (40) particularly reserved for writing said OPC test data is full, and to enable the provision of a smaller OPC area (40), it is proposed according to the present invention that the OPC test data are written in said user area (41, 42) if the OPC area (40) reserved for writing said OPC test data is not usable or not provided on the record carrier (4).

    摘要: The present invention relates to an optical record carrier recording apparatus and method for recording data on a phase-change optical record carrier (55) storing a state information about the location of crystalline and non-crystalline areas of the record carrier (55). In order to provide the possibility to write with different writing speeds on the record carrier, writing means (54) for recording data on the record carrier (55) can be switched between different writing modes. The first writing mode is used if the recording apparatus (5) is in a high power mode, e.g. supplied with power from a mains power supply and if a crystalline (unwritten) area is available on the record carrier (55). If no crystalline area is available or if the recording apparatus (5) is in a low power mode, the second writing mode having a lower writing speed is preferably used.
