Abstract
A digital signal recording apparatus for recording digital signal in synchronization blocks includes a generator for generating a synchronization pattern for indicating the beginning of each synchronization block, a generator for generating an ID data for indicating the sequence of the synchronization blocks, a generator for generating an ID parity for checking the ID data, a generator for generating additional information signal, which is a track width data, a generator for generating audio and video signals. Above data are applied to a pattern generator for generating track data comprising plural consecutive normal synchronization blocks immediately preceded by two mini-synchronization blocks and immediately followed by one mini-synchronization block. Each mini-synchronization block includes the synchrionization pattern, ID data, ID parity, and additional information signal. Each normal synchronization block includes the synchronization pattern, ID data, ID parity, and audio and video signal.
