    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 invention relates to an information carrier for holding user information, the information carrier comprising access information in the form of access information bits for accessing the user information, the access information bits being stored on the information carrier in a variation of a parameter, which variation is detectable by integration detection. The access information bits are scrambled according to a pre-determined scrambling method. By scrambling the access information bits according to a pre-determined scrambling method detection of the access information is not possible as long as the scrambling method is not known. Using the integration detection technique only results in the access information is one knows how the signal obtained after reading-out the area comprising the access information bits must be processed. In this way illegal retrieval of the user information is further prevented.

    摘要: The invention relates to an information carrier 10 comprising a main channel and an auxiliary channel carrying position information 21, according to which some of the least significant bits of the position information 21 are made available as local-position information 22 at a higher rate than the whole position information 21. The information carrier can be in particular an optical disk of recordable type, wherein the auxiliary channel is the wobble channel and the position information 21 is an address. An embodiment of the invention is described of an optical disc based on Blue-ray Disk standard. When an estimate of the current address is already available and the uncertainty only resides in some of the least significant bits, the entire address can be quickly reconstructed as soon as a repetition of the local-position information 22 is acquired. The invention further relates to an apparatus for accessing such an information carrier 10.

    摘要: On a small record carrier the inner section of the record carrier represents a significant amount of storage capacity. A regular ECC block however occupies more than one revolution of the record carrier leading to multiplication of burst errors in a single ECC block. By using two ECC block sizes the multiplication of burst errors is prevented. The transition from the small ECC blocks in the inner annular section to the large ECC blocks in the outer annular section of the disk is positioned where one ECC block from the outer annular section occupies one revolution of the record carrier. Thus an optimum division is achieved between large and small ECC blocks optimizing storage capacity and error correction capabilities.
