Abstract

A video tape recording apparatus records and reproduces digital video and audio signals in the form of coded signals that have a recording format which includes a video signal recording area for recording video data and its respective accompanying information, an audio signal recording area for recording video data and its respective accompanying information, insert and track information and subcode information. Preferably, the recording format includes packs having a pack header having a large data item and a small data item to indicate the format and use of the succeeding pack data. Errors in the recorded and reproduced audio and video signals are detected and the value of the respective accompanying information changed to prevent heading of erroneous stored data and thus prevent propagation of errors.
