ABSTRACT:
Information recording media101and102usable for either a first recording density D1or a second recording density D2each include a user data area106in which user data is to be recorded, a first defect management information area108in which first defect management information for managing a defect area in the user data area is to be recorded, and a second defect management information area109in which second defect management information having an identical content to that of the first defect management information is to be recorded. The first and second defect management information areas108and109are located such that angles θ1and θ2made by start blocks thereof fulfill the relationships of 150°≦θ1≦210° and 150°≦θ2≦210° (θ1: in the case of the first recording density, and θ2: in the case of the second recording density).
