Abstract
Apparatus is adapted for recording and reproducing compressed video data in a selected one of two recording formats, of which a first format is for recording the compressed video data in N (N≧3, and representing an integer) number of tracks on a magnetic tape by dividing the video data into N number of groups, and a second format is for recording data, as auxiliary data independent from the compressed video data, in two of the tracks at both ends, and the compressed video data in (N−2) number of the tracks. In the second recording format, the recording is carried out by setting a data length of an error correction code for sync blocks longer than a data length of another error correction code for sync blocks in the first recording format.
