Part of this standard is the specification of the time and control code record, which forms the longitudinal index track, as specified in ANSI/SMPTE 277M. (1.2) Digital video and audio data derived from various image standards are recorded with a data rate of approximately 1 Gbit/s. All image standards recorded by this format employ the identical track pattern, inner and outer block structure, and modulation code.",
