Patent ID: 8325577

Claim:
A device for recording data and data structures on a write-once storage medium, the data structures comprising space bit map and defect management structures, the device comprising: writing means for recording the data and the data structures on the write-once storage medium; the medium being divided into error correction code clusters, the data being formatted into error correction code cluster data, the data structures comprising the space bit map and defect management structures, the space bit map indicating which error correction code clusters on the medium have been recorded with data; controlling means for generating the data structures and formatting the data into error correction code cluster data and for controlling the writing means; wherein the controlling means are adapted to control the writing means to include in the space bit map address pointers to indicate ranges of error correction code clusters that have been recorded on the write-once storage medium, and to control the writing means to record the data structures at a predefined temporary location in a reserved area on the write-once storage medium and to finalize the write-once storage medium by controlling the writing means for 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.
