DEVICE AND METHOD FOR RECORDING INFORMATION

摘要

A device for recording information records blocks having continuous logical addresses on a record carrier at corresponding physical addresses. The logic al 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 trac k to defect management areas and assignment of the defect management informati on 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 non~streaming 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).
