Method of recording information on a writable optical disc and a system thereof

Abstract

A writable optical disc has at least two chapters comprising a first chapter and a second chapter. Management data including a partition address is written in a management area in each chapter, and information is written in an information recording area after management area in the first chapter. A partition data is written in a partition area after the information recording area of the first chapter. The partition data is erased when writing the second chapter, so that the first chapter is discriminated from the second chapter, and a partition data is written in a partition area of the second chapter after writing of information in an information recording area thereof.

1. A system for recording information on a writable optical disc having an information recording area, a partition area including at least a synchronizing signal and for indicating a data writing finish position, and a management area for writing an address of the partition area, the system comprising:
 retrieving means for retrieving an address of the partition area;  
 determining means for determining whether information exists in the partition area;  
 erasing means for erasing information written in the partition area when the information exists; and  
 means for writing information in an information recording area after the erased partition area.  
 
     
     
       2. The system according to  claim 1  wherein the retrieving means includes control means for retrieving an address of a subsequent partition area when information does not exist in the preceding partition area. 
     
     
       3. The system according to  claim 1  wherein the information in the partition area is a partition data. 
     
     
       4. The system according to  claim 1  wherein the information in the partition area is  including a blank portion. 
     
     
       5. The system according to  claim 1  wherein the writable optical disc is an optical disc on which information can be written only once, and the erasing means is provided for erasing the information in the partition area by writing a predetermined data on the information. 
     
     
       6. A system for recording information on a  an information real disc having an information recording area, a partition area including at least a synchronizing signal and for indicating a data writing finish position, and a management area for writing an address of the partition area, the system comprising:
 retrieving means for retrieving an address of the partition area, said retrieving means including control means for retrieving an address of a subsequent partition area when partition information does not exist in the partition area;  
 determining means connected to said retrieving means for determining whether partition information exists in the partition area corresponding to the address retrieved by said retrieving means;  
 erasing means connected to said determining means for erasing the partition information written in the partition area when the partition information exists; and  
 means for writing other information in an information recording area after the erased partition area, wherein said means for writing other information is connected to said erasing means.  
 
     
     
       7. The system according to  claim 1  wherein the partition area further includes an unwritten area.
