Abstract:
A video data recording and reproducing apparatus comprising:a video data accommodating means for accommodating video data in a predetermined part of a predetermined recording block in predetermined recording units containing one or more frames;an error correction code adding means for generating an error correction code which enables reproduction of each of the recording units of the video data housed in the recording block even if two or more helical tracks worth of data is lost for every recording unit and adding the same to a predetermined part of the recording block;a start/end identification data adding means for adding start/end identification data indicating the start or recording and the end of recording of the video data to a predetermined part of the recording block;a recording means for recording each of the recording blocks accommodating the recording units of the video data and to which the error correction code and the start/end identification data are added over a plurality of helical tracks of the tape recording medium; anda reproducing means for reproducing the recording blocks which have been already recorded on the tape recording medium,wherein when recording other video data (top data) on a tape recording medium on which video data (bottom data) has already been recorded, the recording means starts or ends the recording at a position of the tape recording medium at which the loss of the top data and the bottom data caused due to the recording of the top data does not exceed the error correction capability of the error correction code in accordance with the start/end identification data which had been added to the reproduced recording blocks accommodating the bottom data and the recording blocks accommodating the top data.
