Method of recording data on a write once disc, and the write once disc

Abstract

A method of recording data on a write once disc, and the write once disc. The write once disc includes a lead-in zone, a data area, and a lead-out zone. The write once disc includes a predetermined area storing area allocation information which indicates whether at least one section of the data area is allocated for disc defect management. In the disc and method, area allocation information specifying a structure of the data area is recorded on the disc, thus allowing a recording/reproducing apparatus to recognize the data area structure. Therefore, allocating areas, such as a spare area, for disc defect management other than an area for storing user data, to the data area is possible. The allocation of the areas for disc defect management to the data area enables effective use of the write once disc.

1 . A method of recording data on a write once disc including a lead-in area, a data area, and a lead-out area, comprising:
 recording area allocation information in a temporary disc defect structure (TDDS) of a temporary defect management area (TDMA) formed in a predetermined area on the disc, which indicates whether at least one section of the data area is allocated for disc defect management;   recording data in the data area on the disc and performing disc defect management; and   recording the area allocation information recorded in the temporary disc defect structure (TDDS) in a defect management area (DMA),   wherein the at least one section comprises a spare area, a temporary disc defect structure (TDDS) area, a temporary defect list (TDFL) area, or the temporary defect management area (TDMA).   
   
   
       2 . The method of  claim 1 , wherein the area allocation information indicates a size of the at least one section as 0 when the at least one section of the data area is not allocated. 
   
   
       3 . A write once disc with at least one record layer, comprising:
 at least one data area which stores user data; and   at least one predetermined area which stores area allocation information, which indicates whether at least one section of the at least one data area is allocated for disc defect management, wherein the at least one predetermined area is formed in a temporary disc defect structure (TDDS) of a temporary defect management area (TDMA), and the area allocation information recorded in the temporary disc defect structure (TDDS) is recorded in a defect management area (DMA), and   the at least one section comprises a spare area, a temporary disc defect structure (TDDS) area, a temporary defect list (TDFL) area, the temporary defect management area (TDMA), or combinations thereof.   
   
   
       4 . The disc of  claim 3 , wherein the area allocation information indicates a size of the at least one section as 0 when the at least one section of the at least one data area is not allocated.
