    摘要: A device for recording records information in blocks having logical addresses at a physical address (52) in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information, such as remapping tables, maintained in defect management areas. For avoiding remapping of real­ time information, such as video, a series of blocks (42) having a continuous logical address range is recorded in a corresponding allocated physical address range. In the event of a defect interrupting the allocated physical address range local offset information is generated for adding an offset to a local range of physical addresses in said address translation for skipping (61) the defect. The blocks logically following the last block before the defect are written at physical addresses following the defect, and an end portion (62) that extends beyond the allocated physical address range due to the defect, is accommodated elsewhere.

    摘要: A recording medium (D) comprises a file system area (FSA), a data area (DAA) and an initial defect management area (DMA). A system comprises a drive (DR) for writing data (DA) to or reading data (DR) from the data area (DAA) or the defect management area (DMA), and a host (H) for sending data (DA) to or for receiving data (DA) from the drive (DR) when the drive (DR) is in a mounted state wherein a file system (FS) in the file system area (FSA) is available to the host (H). The method of accessing such a recording medium (D) detects (S1) whether a shortage of free space in the defect management area (DMA) is to be expected, and if yes, allocates (S2) supplemental defect management area (SDMA) at the cost of the data area (DAA). The file system (FS) is adapted to reflect the latest state of available data area (DAA) and the allocated supplemental defect management area (SDMA). The file system (FS) is adapted during an adaptation period related to a mounting or an unmounting phase wherein the host (H) mounts or unmounts the drive (DR). The host (H) unmounts or releases the drive (DR) when no further data has to be exchanged between the host (H) and the drive (DR).

    摘要: A device records information in blocks having logical addresses at a physical address in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information (52,53,61,64), which includes defect entries indicating locations for replacing defective physical addresses. A read-only state of the record carrier is obtainable via a no-replacement state indicated by substantially none of the defect entries being free for use. The device has a read-only unit for setting the record carrier to the read-only state by reading original replacement information indicating a writable state, storing the original replacement information (60) in a hidden area, and writing defect management information (61) that is modified to the no-replacement state. The record carrier may be re-opened by retrieving the original replacement information (60) from the hidden area.

    摘要: A recording apparatus for recording digital information signals on a removable rewritable disc like recording medium has been proposed. The apparatus comprises writing means (21, 22, 25) for recording the digital information signals and control means (20) for controlling the recording. The apparatus is capable of performing initialization, formatting and defect management of a rewritable medium. Further, the apparatus is capable of storing first file system data in a user area (UA) and second file system data in a general application area (GAA) on the medium. The control means (20) are adapted to modify defect management data on the medium in order to block write access to UA under control of the first file system. This prevents systems unaware of the second file system data on the medium from modifying contents of UA.

    摘要: A device for recording information records blocks having continuous logical addresses on a record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses in dependence of defect management information, which includes assignment information indicative of assignment of physical addresses in first parts of the track to at least one user data area, assignment of physical addresses in second parts of the track to defect management areas and assignment of the defect management information to the defect management areas. A data type of recorded information is detected, in particular the type being streaming for real-time data like digitally encoded video, or non­streaming for random data like computer data files. The device has defect management area reassignment means for changing said assignment information in dependence of the data type. For example a contiguous defect management layout (54) is converted into a distributed layout (55).
