<P>PROBLEM TO BE SOLVED: To provide a method or the like for determining whether a defect exists in an information recording medium. <P>SOLUTION: A method includes, in order to manage an information recording medium including a spare area for a replacement block to replace a defect block generated in a user data area of the medium, a step for seeking a defect entry in which state information that indicates that the defect block or the replacement block is reinitialized without certification is set from a defect list including state information of the defect block and the replacement block, and a step for performing certification with respect to the defect block or the replacement block registered in the sought defect entry. As a result, generated defect information can be effectively rearranged by performing quick reinitialization without certifying a disk, thereby the performance of a drive system can be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
