    摘要： Information recording media 101 and 102 usable for either a first recording density D1 or a second recording density D2 each include a user data area 106 in which user data is to be recorded, a first defect management information area 108 in 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 area 109 in 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 areas 108 and 109 are located such that angles θ1 and θ2 made 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).
