    • The latest management data recorded in a recording medium is read. Then, it is judged whether the fault is in this latest management data or not. When it is judged the fault is not in this latest management data, a data size of user data under the management of this latest management data is compared with a data size of the user data recorded actually in the recording medium. In the judgment explained above, when the latest management data cannot be read, when it is judged the fault is in the latest management data or when it is judged a data size of user data under the management of the latest management data is not identical to a data size of the user data recorded actually in the recording medium, management data can be updated by analyzing the user data recorded in the recording medium. Thereby, there is provided a repair technique for the recorded data in response to an accidental shut-off condition of power supply in a data recording apparatus for recording user data and management data used for management of such user data to the recording medium.
    • 读取记录在记录介质中的最新管理数据。 然后,判断故障是否处于最新的管理数据。 当判定故障不在该最新管理数据中时,将在该最新管理数据的管理下的用户数据的数据大小与实际记录在记录介质中的用户数据的数据大小进行比较。 在上述判断中,在不能读取最新的管理数据的情况下,当判定出故障处于最新的管理数据时,或者当判定在最新管理数据的管理下的用户数据的数据大小与 实际记录在记录介质中的用户数据的数据大小,可以通过分析记录在记录介质中的用户数据来更新管理数据。 因此,为了将记录用户数据的数据记录装置中的电源的意外关闭状况和用于管理这些用户数据的管理数据记录在记录介质上,为记录数据提供了修复技术。
