Pictures in number indicated by a value (3 in one example) of M in a GOP structure are set as one unit. AUX data (denoted by U in FIG.) related to those pictures, audio data (denoted by A in FIG.) corresponding to those pictures, and AUX data (denoted by X in FIG.) related to the audio data are arranged together at the head of 16 tracks that undergo interleaving. Subsequent to those data, one unit of pictures (3 pictures in one example) is arranged. An HD video signal and an HD audio signal can be recorded and played back with certainty.

Magnetic tape recording apparatus and method, magnetic tape playback apparatus and method, format for magnetic tape, and storage medium product

A magnetic-tape recording apparatus for recording digital data on a magnetic tape by a rotating head includes a first obtaining unit for obtaining first-group data, including video data, audio data, or search data. A second obtaining unit obtains second-group data, including sub-code data related to the first-group data. A synthesizing unit synthesizes the first-group data and the second-group data such that they are continuous without any space disposed therebetween, on each of two sub-tracks formed with a gap sandwiched therebetween on a track in the magnetic tape. A sending unit sends data synthesized by the synthesizing unit to the rotating head in order to record the data on the magnetic tape.
