Abstract
A device for recording data and data structures on a write-once storage medium. The device has writing means for recording the data and the data structures and controlling means for generating the data structures and controlling the writing means. The data structures comprise space bit map and defect management structures. The controlling means are adapted to record the data structures at a predefined temporary location on the write-once storage medium and to finalize the write-once storage medium by recording the data structures at a predefined fixed location as defined for a rewritable storage medium.
Claims8
A device for recording data and data structures on a write-once storage medium, the device comprising:
- writing means for recording the data and the data structures, the data structures comprising a space bit map and defect management structures;
- controlling means for generating the data structures and controlling the writing means;
- the controlling means being configured to include in the space bit map address pointers to indicate ranges of clusters that have been recorded, and to record the data structures at a predefined temporary location in a reserved area on the write-once storage medium and afterwards to finalize the write-once storage medium by recording the data structures at a predefined fixed location as defined for a rewritable storage medium, the predefined fixed location being different than the predefined temporary location.
A method of recording data and data structures on a write-once storage medium, the data structures comprising a space bit map and defect management structures, the method comprising steps of:
- providing in the space bit map address pointers to indicate ranges of clusters that have been recorded;
- recording the data structures at a predefined temporary location in a reserved area on the write-once storage medium;
- finalizing the write-once storage medium by recording the data structures at a predefined fixed location as defined for a rewritable storage medium.
A write-once storage medium comprising data and data structures comprising space bit map and defect management structures, wherein:
- the space bit map includes address pointers to indicate ranges of clusters that have been recorded,
- the data structures are recorded at a predefined temporary location in a reserved area on the write-once storage medium, and
- the write-once storage medium is finalized by recording the data structures at a predefined fixed location as defined for a rewritable storage medium.
A non-transitive computer readable medium encoded with instructions for controlling a processor for operating a method for recording data and data structures on a write-once storage medium, the data structures comprising space bit map and defect management structures, the method comprising:
- providing in the space bit map address pointers to indicate ranges of clusters that have been recorded;
- recording the data structures at a predefined temporary location in a reserved area on the write-once storage medium;
- finalizing the write-once storage medium by recording the data structures at a predefined fixed location as defined for a rewritable storage medium.
