    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 remapping information indicative for translating a logical address initially mapped to a physical address exhibiting a defect to an alternate physical address in a defect management area. The device has a continuous data detection unit for detecting a logically continuous data, and a defect management reorganizing unit. The physical addresses of remapped logical addresses in the logically continuous data are determined, and the defect management information is reorganized by remapping at least one of the remapped logical addresses to a different defect management area. During read-out the remapped logical addresses in the logically continuous address range are retrieved from a single defect management area.

    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, 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 in a hidden area, and writing defect management information that is modified to the no-replacement state. The record carrier may be re-opened by retrieving the original replacement information from the hidden area.

    摘要: A recording apparatus for recording digital audio/video 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 data in replacement areas instead of defect areas, which have been determined to be defective according to rules of the defect management. The control means (20) are adapted to re-record data from the replacement areas in the defect areas in order to improve playability of digital audio/video signals stored on the medium.

    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 for recording records a series of blocks (42) having continuous logical addresses, e.g. digitally encoded video, on a record carrier at a corresponding physical address range. Some physical addresses are assigned to defect management areas (43). The logical addresses are translated into the physical addresses in dependence of the defect management information. The device has contiguous recording means for detecting if the allocated physical address range is interrupted by a subset of physical addresses assigned to a defect management area. If so, the subset of physical addresses is reallocated to the user data area. The series of blocks (42) is contiguously recorded extending over the subset of physical addresses. The defect management area may be eliminated, shifted to a new location (51) after the end of the recorded file or shifted to the end of the medium.

    摘要: A device for recording records blocks of information on logical addresses on a record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses in dependence on defect management information that includes defect information on a defective status of physical addresses and remapping information on translating a logical address initially mapped to an initial physical address to an alternate physical address. The device has a real-time storage unit for writing real-time information blocks (77) to respective initial physical addresses irrespective of the defective status. When recording at a defective status location (76), the real-time information block is temporarily stored in a memory (80). In a separate period, when the writing of real-time information blocks is suspended, said temporarily stored real-time information blocks are additionally written to alternate physical addresses (81). The defect management information (73) is updated to indicate that the real-time information block is present at both locations.

    摘要: A device for recording information records blocks, having continuous logical addresses on a record carrier at corresponding physical addresses, translates logical addresses into physical addresses in dependence of defect management information. The, defect management information 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, such as the type being streaming for real-time data like digitally encoded video, or non-streaming for random data like computer data files. The device reassigns defect management area for changing the assignment information in dependence of the data type. For example, a contiguous defect management layout is converted into a distributed layout.

    摘要: A device for recording blocks of information on logical addresses on a record carrier at corresponding physical addresses. The logical addresses are translated into the physical addresses in dependence of remapping information (57, 63) indicative for translating a logical address initially mapped to a physical address to an alternate physical address in a remapping area (55), for example for defect management. The device can operate at two addressing modes corresponding to recording user data and additional data in separate areas. The device has storage means for storing additional data (54, 62) while maintaining addressing mode for storing data in the user area (53), the storage means being arranged for assigning an additional data physical address to the additional data, adapting the remapping information (57, 63) to indicate that the additional physical address is not available for storing user data, and directly recording the additional data at the additional data physical address.

    摘要: A recording system records blocks of information on a record carrier according to a file management system. Data space on a partly and fragmented recorded record carrier (60-68) is managed as follows. The information includes a first type of information, such as video, and a second type, such a general purpose data. The first type has extent allocation requirements that include requiring an extent to accommodate a multitude of information blocks in a consecutive range of addresses and the extent to have at least a predetermined extent size. Data space is managed by selecting at least one partly recorded data area (67,63,68) of at least the extent size which data area contains information blocks (63) at recorded addresses, and subsequently creating a free data area (74) on the record carrier by moving the information blocks from the recorded addresses in the partly recorded data area to different addresses (73) outside the free data area (74) and correspondingly adapting the file management data.
