Abstract 



This invention provides a method for creating/writing defect management information of an 
information recording medium and an apparatus and optical disc based on the method. In the 
present invention, it depends on the type of data to be reproduced whether or not defective 
sectors which are detected during reproduction operation are replaced with non-defective 
sectors. If read-out errors are detected in reproducing non-audio/video data, linear replacement 
algorithm is applied to the corresponding defective sectors. On the other hand, in case of 
audio/video data, location information of the corresponding defective sectors is just kept without 
any sector replacement.
