Patent ID: 7333411

Claim:
An optical recording method for recording data onto an optical recording medium, comprising: partitioning a data zone into a first management information area, serving as file system area, a second management information area, corresponding to a reproduction management system for real time data, and a data area in which the real time data are recorded; dividing final processing into padding processing by executing padding recording to a predetermined last recording position; first management information processing of recording a file system, prepared in a format compatible with another file system and including information for managing reproduction management information recorded in the second management information area and the real time data recorded in the data area, in the first management information area; second management information processing of recording a reproduction management system, including a reproduction management information managing reproduction of the real time data recorded in the data area, in the second management information area; recording processing of preparing a lead-in area and a lead-out area; judging, before starting every dividing final processing, whether remaining battery capacity is sufficient for completing execution of dividing final processing by confirming the remaining battery capacity; executing the dividing final processing and storing, in a non-volatile memory, a notification of completion of one dividing final processing every time the dividing final processing is completed, when the remaining battery capacity is sufficient; interrupting the dividing final processing when the remaining battery capacity is not sufficient; and restarting the interrupted processing subsequent to the dividing final processing which has been stored in the non-volatile memory, at the time point when the remaining battery capacity becomes sufficient.
