    • 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).

    • An information recording apparatus is provided with a recording controller for recording data on an information recording medium, a verification controller for verifying whether or not the recorded data can be correctly reproduced, a continuous recording controller for providing a gap region of a specified interval between a verification region and a recording region and successively performing a verify processing and a record processing with rotation waiting in between, an error region discriminator for discriminating an error region in the event of an error in the process of performing the verify processing and the record processing, and an error processor for performing an error processing according to the error region. The error processor performs an error processing different from the one performed when an error occurred in either one of the verification region and the recording region if an error is discriminated to have occurred in the gap region. By this construction, a recording time is shortened and it is prevented that data cannot be recorded on the information recording medium.
    • 信息记录装置设置有用于在信息记录介质上记录数据的记录控制器,用于验证记录数据是否可以被正确再现的验证控制器,用于提供记录数据之间的间隔区域的连续记录控制器 验证区域和记录区域,并且在循环等待中继续执行验证处理和记录处理,用于在执行验证处理的处理和记录处理的过程中识别错误区域的错误区域鉴别器, 以及用于根据误差区域执行错误处理的错误处理器。 错误处理器执行与当在差异区域中出现错误时,在验证区域和记录区域中的任一个中发生错误时执行的错误处理。 通过这种结构,缩短了记录时间,并且防止了数据不能被记录在信息记录介质上。
