    摘要: An information data composed of a predetermined quantity converted from input data and an information data parity for use in detecting or correcting an error in the information data are formulated. An ID comprising information including position information indicative of a position of the information data relative to a recording medium, and an ID parity for use in detecting or correcting an error in the ID are formulated. Then, a sync pattern is formulated, followed by formulation of a sync block comprised of the sync pattern, the ID, the ID parity, the information data and the information data parity. A plurality of the sync blocks are connected together to provide a recording area. This recording area forms a track together with other recording areas. Three or more consecutive tracks forms a minimum editing unit with which recording or reproduction is carried out. Each minimum editing unit has a plurality of the sync blocks having the same information data, and the plural tracks forming each minimum editing unit includes at least one track other than those positioned on respective opposite sides of the minimum editing unit.

    摘要: 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.
