ABSTRACT:
When a previous recording of data on a write-once optical disc is incomplete, the previous recording is processed to enable it to be read, and to enable additional data to be recordable on the write-once optical disc following the incomplete previous recording. The previous recording, when incomplete, lacks at least an end portion that would be included in the previous recording when complete. The previous recording is tested to determine whether it is incomplete. When the previous recording is detected as being incomplete, the position of the end of the previous recording is determined, a pseudo signal is generated for recording on the write-once optical disc, and the pseudo signal is written on the write-once optical disc, starting at the previously-determined position of the end of the previous recording. Writing the pseudo signal appends to the previous recording an additional recording that includes a replacement for the end portion lacking from the incomplete previous recording.
