<P>PROBLEM TO BE SOLVED: To efficiently perform management on an optical recording medium, in an optical recording medium recording/playback device and its method for managing a defective area of the optical recording medium and in a rewritable optical recording medium. <P>SOLUTION: A linear replacement control (LRC) bit is added to a secondary defective list (SDL) entry so as to discriminate a defective block information that is listed at the SDL entry according to linear replacement algorithm from a defective block information that is listed at the SDL entry according to a skipping algorithm, thereby the optical recording medium recording/reproducing apparatus is allowed to transmit correct information to a host. Furthermore, when a defective block requiring a new replacement block is found while recording or reproducing data when spare area is full, the LRC bit is set in the SDL entry along with the location information of the defective block so as to indicate that the corresponding SDL entry is made when the spare area is full. <P>COPYRIGHT: (C)2009,JPO&INPIT |
