Abstract
The invention provides a reliable write method of data on an optical record carrier without changing the conventional configuration of an information recording apparatus. The invention uses the errors occurred in reading ATIP codes and/or the reflected signal from the surface of the record carrier to decide if the storage unit on the record carrier is eligible to store data. The defective storage units are labeled as unrecordable.
