Abstract
An apparatus and method for addressing data losses when power to a digital recorder is unexpectedly interrupted during recording, and a the file management information needed to play back digital content is not completely written to a disc. The recovery process for correcting inconsistencies between the AV data and management information left on the disc is time-consuming. By recording the recovery data used for the data recovery process when power is turned on again, the management information can be recompiled based on the recovery data. Thus, inconsistencies between the AV data and management information can be corrected. Additionally, AV data and recovery data in this case can be written alternately to contiguous areas on the disc.
