A magnetic tape recording apparatus uses a rotary head to record digital data
on
a magnetic tape. The magnetic tape recording apparatus includes a first acquisition
unit for acquiring a first group of data including video data, audio data, or search
data, a second acquisition unit for acquiring a second group of data including
subcode data related to the first group of data, a synthesizing unit for synthesizing
data by combining the first group of data and the second group of data so that
both groups of data are continuous on the tracks of the magnetic tape without being
separated, and a supply unit for supplying the synthesized data to the rotary head
so that the synthesized data is recorded on the magnetic tape.
