Patent ID: 8521003

Claim:
A recording apparatus for recording data to a rewritable record medium, comprising: 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 that a computer software program that synchronously reproduces a moving picture and so forth can handle without need to use a special hardware device; and recording means for recording data having the file structure to the record medium, wherein the file structure has (a) a first data unit of data, (b) a second data unit being a set of a plurality of first data units successively recorded, and (c) a data portion describing management information for each track of the record medium, wherein a plurality of second data units is correlated with a successive record length of the record medium and a part of each second data unit is pre-allocated as a reserve area, the reserve area recorded after original data is recorded wherein post-recorded data in the reserve area is reproduced in synchronization with pre-recorded data in the successive record length of each second data unit, and wherein the data portion contains (a) information representing a data type of the first data unit, (b) information representing a record sequence of the plurality of first data units, (c) information representing a number of successive first data units for each data type recorded on a designated track, (d) information representing a number of times of which successive first data units are repeatedly recorded on a track for each data type, and (e) information identifying a beginning first data unit corresponding to the second data unit recorded in the successive record length.
