• receiving, from an external device, an obtaining request for the management information, said obtaining request including designation of a specific management information area;
• obtaining the management information relating to the data recording from the specific management information area designated in the received obtaining request;
• reporting, to the external device, the management information relating to the data recording obtained from the designated specific management information area;
• and
• determining whether or not the designated specific management information area corresponds to a specific default value, said specific default value being set in advance with respect to the designation of the specific management information area,
• wherein, when the designated specific management information area is the specific default value, the step of reporting the management information reports, to the external device, the management information relating to the data recording obtained from a last management information area.

A data management information obtaining program installed in a computer of an information reproducing apparatus reproducing information of an information recording medium in which a record area is divided into a plurality of data areas, data is recorded for each of the divided data areas, management information relating to the data recording is recorded in predetermined management information areas, and the management information is updated and recorded in a new management information area every time predetermined data recording is completed, said data management information obtaining program for causing the computer to carry out a management information obtaining process comprising the instructions of:

• causing the computer to receive, from an external device, an obtaining request for management information, said obtaining request including designation of a specific management information area;
• causing the computer to obtain the management information relating to the data recording from the specific management information area designated in the received obtaining request;
• and
• causing the computer to report, to the external device, the management information relating to the data recording obtained from the designated specific management information area, and
• wherein the record area includes at least one session having a plurality of tracks as the data areas, and the management information relating to the data recording recorded in each of the management information areas includes all track information of the session and all session information of sessions recorded before the session.
