Abstract
A method for video data can process the backup a VCD with damage zones to overcome a deficiency of the conventional CD-RW drive being incapable of backing up a VCD with damage zones. The method is to read data saved in a directory zone of the data storage zone first and, then, confirm location of the damage zone. Next, the method allows the optical pickup to skip the damage zone during the process of backing up the data in the data storage zone so as to complete the backup job for the entire data storage zone without accessing the damage zone.
