Abstract:
1. A recording apparatus for recording, on an optical disk recording medium, one or a plurality of data, data management information for managing N (N is an integer) pieces of the data as a data group and total management information for managing M (M is an integer) pieces of the data group, comprising: means for recording, on the total management information area of the optical disk recording medium, time zone information (TM_ZONE) indicating a time difference between a world standard time and a standard time in a predetermined location; means for recording, on respective data management information area of the optical disk recording medium, recording time zone information (REC_TM_ZONE) at a time of recording data, indicating a time difference between the world standard time and a standard time in a location where the data of the data managed by the data management information have been recorded; means for recording, on respective data management information area of the optical disk recording medium, first data recording time information indicating a recording time of data first recorded on the data group in accordance with the standard time indicated by the time zone information (TM_ZONE); and means for recording, on respective data management information area of the optical disk recording medium, second data recording time information indicating a recording time of data last recorded on the data group in accordance with the standard time indicated by the time zone information (TM_ZONE), wherein the means for recording the first and second data recording time information uses a recording time (CUR_TM) at a local time and the time zone information (TM_ZONE) at a time of recording the data at a local time and the recording time zone information (REC_TM_ZONE) at the time of recording the data, to obtain the data recording time information by calculation of (CUR_TM)+(TM_ZONE)−(REC_TM_ZONE).
