Abstract:
1. A magnetic tape recording apparatus for recording digital data on a magnetic tape by using a rotary head, comprising: first acquisition means for acquiring a first group of data including video data, audio data, or search data, wherein the first group of data has a sector structure of a main data area storing said video data, said audio data, or said search data and a sync block header identifying the type of the main data; second acquisition means for acquiring a second group of data including subcode data related to said first group of data; synthesizing means for synthesizing data by combining said first group of data and said second group of data so that both groups of data are continuous on the tracks of said magnetic tape without being separated; and supply means for supplying the synthesized data to said rotary head so that the synthesized data is recorded on said magnetic tape, wherein said first acquisition means acquires high definition video data as said video data; said first acquisition means further comprises compression means for compressing the high definition video data acquired by said first acquisition means; and said synthesizing means performs combination processing on the high definition video data compressed by said compression means.
