<P>PROBLEM TO BE SOLVED: To efficiently perform management of defective area of an optical recording medium and a rewritable optical recording medium on the 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 playback data when spare area is full, instead of carrying out linear replacement, 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 |
