Abstract
A playback apparatus plays back data from a recording medium having recorded thereon a file system representing association between identification information for identifying a file and a position where the file is recorded, pieces of segment data constituting the file, and markers for the respective pieces of segment data, each marker that is recorded after a key marker specified in certain cases including location information of the key marker. The playback apparatus includes a detector that detects a last marker in a recording area where data has been recorded on the recording medium but has not been reflected on the file system, and a restoration processor that executes a restoration process of reflecting on the file system segment data that has been recorded on the recording medium but has not been reflected on the file system, based on the location information of the key marker and the location information of segment data.
