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.
