    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 storing first file system data and second file system data addressing user data in a user area (UA) on the medium. The control means (20) are adapted to define partitions for both file systems such that the partitions start at the same location and to store the second file system directory entries outside the first file system partition. This reduces time and space necessary for handling the second file system data by allowing two file systems to share their file entries, while protecting the second file system directory entries from being erased when the medium is under control of the first file system.

    摘要: A device for recording 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, such as primary and secondary defect lists and remapping tables, maintained in defect management areas (61). The defect management information includes assignment information indicative of assignment of physical addresses in parts of the track to user data areas or to defect management areas. The device has assignment means for dynamically adapting the assignment information in dependence of detected defects (54) by assigning an additional physical address range to an additional defect management area (61). The additional physical address range starts near the detected defect (54). Hence the defect (54) is covered by a defect management area, which reduces the need for remapping.

    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 method of recording digital information signals on a removable rewritable disc like recording medium, the method comprising recording user data on a logical area of the disc and, prior to removal of the disc out of a recording/reproducing apparatus, finalizing the disc with a lead-in and lead-out area comprising predefined medium format data. A general purpose area within the logical area for other use than recording of user data, is being reserved. Such as use may be for example defect management. Further the method involves interrupting recording a lead-in area or a lead-out area at predefined splice points whenever a request for user data is made.

    摘要: The present invention relates to a method of ensuring seamless playback of video files stored as a BDFS (Blu-ray Disc File System) file in a UDF (Universal Disk Format) file system using a UDF and BDFS combination format, said method of seamlessly playing back the video files comprising the step of­ creating a BDFS extent by mapping it to at least one UDF extent, wherein said mapping is based on rules defined by BDFS.
