发明名称 Record carrier having a main file system area and a virtual file system area
摘要 The present invention relates to a recordable record carrier having a user area (UA) for storing user data and a management area (MA) for storing management data. The invention further relates to a recording apparatus for recording information on such a record carrier and a corresponding recording method. In some applications it is useful to translate the main file system into an alternative virtual file system. To reduce the mount times and power consumption needed for reconstruction of the virtual file system, it is proposed that the management area (MA) comprises a main file system area ( 70 ) for storing main file system data (mFS), a virtual file system area ( 71 ) for storing virtual file system data (vFS) in a raw format, and an indicator area ( 72 ) for storing an indicator (ID) indicating whether the main system data (mFS) and the virtual file system data (vFS) are mutually consistent. Only if the indicator (ID) indicates an inconsistency does the virtual file system data (vFS) need to be reconstructed from the main file system data (mFS) when the virtual file system data (vFS) is required by an application. Otherwise, the virtual file system data (vFS) can be directly retrieved from the record carrier without reconstruction.
