The data recorded may be digital video and audio data of various image standards up to approximately 1 Gbit/s as specified in ANSI/SMPTE 278M. (1.2) Also specified are the content, format, and recording method of the longitudinal record containing tracking information for the scanning heads associated with the helical records, and the longitudinal index and cue tracks. (1.3) In addition, this standard specifies the principal properties of the magnetic tape used for 19-mm type D-6 digital recording.",
