Patent ID: 8125866

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; controlling means for generating the data structures and controlling the writing means; during wherein as the data is recorded, the controlling means are adapted to control the writing means to record the data structures on the write-once storage medium at a predefined temporary location in a reserved area on the write-once storage medium and after the data structures are recorded in the temporary location, then the controlling means are adapted to control the writing means to finalize the write-once storage medium by recording the data structures on the write-once storage medium at a predefined fixed location on the write-once storage medium, wherein the predefined fixed location is a location on the write-once storage medium that corresponds to a location that is predefined for a rewritable storage medium, wherein the predefined fixed location is a different location on the write-once storage medium than the predefined temporary location, and wherein the space bit map indicates written and free areas of the write-once storage medium, the defect management structures indicating the locations of rewritten data for respective track defects of the write-once storage medium.
