Abstract
A digital video signal of one frame is recorded as diagonal tracks on a magnetic tape by four recording heads. One frame is recorded as six segments (twelve tracks). Adjacent tracks is reverse azimuths. In each track of even segments, an auxiliary data sync block is recorded at the last position of a video sector v1. In each track of odd segments, an auxiliary data sync block is recorded at the beginning position of a video sector v1. Since an auxiliary data sync block is recorded at spaced positions on a tape, it can be prevented that an auxiliary data cannot be read at all on a tape scrached in the longitudinal direction.
Claims9
A digital information signal recording apparatus for recording a digital information signal onto diagonal tracks of a recording medium, such as a tape, comprising:
- record-signal forming means for encoding an input digital information signal with an error correction code to form record-data of a plurality of data units, some of said data units including encoded data and at least one data unit being composed of auxiliary data other than the input digital information signal;
- and
- recording means for successively recording record-data onto diagonal tracks of said recording medium so that a plurality of data units including encoded data and at least one data unit being composed of auxiliary data are both recorded on one track of the recording medium, and wherein the record-data recorded on each track is formed in such a manner that the data unit of the one track composed of the auxiliary data is recorded apart from the data units composed of similar type and content auxiliary data in other tracks adjacent to and in the vicinity of the one track.
A digital information recording method for recording a digital information signal onto diagonal tracks of a recording medium, such as a tape, comprising the steps of:
- encoding an input digital information signal with an error correction code to form record-data of a plurality of data units, some of said data units including encoded data and at least one data unit being composed of auxiliary data other than the input digital information signal;
- and
- successively recording record-data onto diagonal tracks of said recording medium so that a plurality of data units including encoded data and at least one data unit being composed of auxiliary data are both recorded on one track of the recording medium, and wherein the record-data recorded on each track of the recording medium is formed in such a manner that the data unit of the one track composed of the auxiliary data is recorded apart from the data units composed of similar type and content auxiliary data in other tracks, adjacent to and in the vicinity of the one track.
