Apparatus and method of recording a record map and write-once disc therefor

摘要

A method and apparatus for recording a record map, and a write-once disc therefore. The write-once disc has at least one recording layer and stores a record map which identifies locations of consecutive data blocks that are occupied with data or not occupied with data. Accordingly, the amount of data to be recorded on the write-once disc to indicate the data-recording status of the write-once disc is reduced so that the recording area of the write-once disc can be more efficiently used.
