Abstract

Abstract An information recording medium such as an optical recording medium or an optical disk comprises a first defect managing region into which an initial defective region is registered; and a second defect managing region into which a defective region occurring after the registration of the initial defective region into the first defect managing region is registered. In a recording and reproducing apparatus operating on such an information recording medium, identification information is reproduced from each of sectors in the first and second defect managing regions, the identification information representing whether the sector belongs to the first defect managing region or the second defect managing region. Defect managing information is recorded into and erased from each of the sectors in accordance with the reproduced identification information.
