ABSTRACT:
A recovery method for recording to a write-once disc. The recovery method includes: sequentially reading data within a plurality of Data Control Blocks corresponding to respective sessions on the write-once disc; utilizing data included in the Data Control Blocks to establish address information corresponding to each closed session; determining whether the write-once disc is finalized or not according to existence of a lead-out zone; reading a TOC (table of content) block of a TOC area; utilizing the address information stored in a memory of an optical disc drive to recover the TOC block and then storing the TOC block into the memory of the optical disc drive as data of the TOC block prepared for the next recording operation when reading the TOC block fails and the write-once disc is not finalized; and completing the loading operation of the write-once disc to make the write-once disc enter a recordable status.
