Method for choosing the defect detection mode of an optical storage device

Abstract

At least one detection area on an optical storage medium is allocated for data storage first, and then the detection area is set to a defect detection mode of either write detection or write verification, depending on the number of defects stated in a previous defect record. If the detection area is the write detection mode and the number of accumulated defects exceeds a default threshold value, the detection area would be configured anew and thereby set to a defect detection mode of write verification.

1 . A method for choosing the defect detection mode of an optical storage device, comprising the steps of: 
 designating at least one detection area on an optical storage medium as a data storage area;    setting the detection area to a write detection mode for defect detection;    writing data into the detection area at a write detection mode; and    setting the detection area to a write verification mode for defect detection in place of the write detection mode if the number of accumulated defects in the detection area exceeds a default threshold value.    
   
   
       2 . The method for choosing the defect detection mode of an optical storage device of  claim 1 , further comprising the steps of: 
 counting and recording the defects in the detection area; and    setting the detection area to a write verification mode for defect detection if the number of the defects in the detection area exceeds the default threshold value.    
   
   
       3 . The method for choosing the defect detection mode of an optical storage device of  claim 1 , wherein the detection area is one of a plurality of data areas on the optical storage medium.  
   
   
       4 . The method for choosing the defect detection mode of an optical storage device of  claim 1 , wherein the detection area is one of a plurality of data packets on the optical storage medium.  
   
   
       5 . The method for choosing the defect detection mode of an optical storage device of  claim 1 , wherein there is only one detection area, which includes all the data storage areas of the optical storage medium.
