Patent ID: 7853116

Claim:
A recording apparatus for recording data to a rewritable record medium, comprising: reading means for reading a recorded data from the rewritable record medium; encoding means for encoding the data corresponding to a predetermined compressing and encoding system; converting means for converting a data structure of encoded data that is output from the encoding means into a file structure; and recording means for recording data having the file structure to the record medium, wherein the file structure has a first data unit having audio chunks and video chunks, a second data unit having a plurality of tracks for managing the audio chunks and video chunks, and a data portion having successive length information for each of the plurality of tracks of the second data unit, wherein the recording apparatus determines whether the recorded data is reproduced successively based on data included in the data portion, a seek time corresponding to a track jump, and a time margin caused by a fabrication fluctuation of the reading means, wherein the successive length information indicates a successive record length of each of the plurality of tracks in units of the audio chunks and video chunks, wherein the data portion includes information representing a number of repeats of each track, wherein the file structure has a hierarchy, the data portion being placed in the highest hierarchical level, wherein the plurality of second data units is correlated with a successive record length of the record medium, and wherein the data portion contains a time length and a data length of the second data unit recorded in the successive record length.
