Data recording method for optical disk drive

Abstract

A data recording method for an optical disk drive is implemented by the following steps. First, one or more data blocks are encoded and recorded sequentially, and it detects if a buffer under run occurs. If a buffer under run occurs, the recording does not stop immediately until at least the main data of the data block being currently recorded have been recorded completely. Afterwards, it restarts to encode and record from the data block next to the data block where the recording stops. Moreover, the recording also can stops if a servo error is detected, and the data restart to encode and record from the data block where the recording stops or at least one data block preceding the data block where the recording stops.

1 . A data recording method for an optical disk drive, the method comprising: 
 encoding and recording data blocks;    detecting whether a servo error occurs;    stopping a recording operation if a servo error occurs; and    restarting to encode and record data from the data block where the recording stops or at least one data block preceding the data block where the recording stops.    
   
   
       2 . The method of  claim 1 , wherein the data restart to encode and record from the beginning of the data block where the recording stops.  
   
   
       3 . The method of  claim 1 , wherein the servo error is caused by vibration, laser defocusing, track-locking error or buffer under run.  
   
   
       4 . The method of  claim 1 , further comprising recording a rewritable disk.  
   
   
       5 . The method of  claim 1 , further comprising recording a digital video drive (DVD).
