DIGITAL INFORMATION SIGNAL RECORDING DEVICE AND METHOD

摘要

Digital video signals of one frame are recorded as oblique tracks on a magnetic tape by four recording heads. One frame is recorded as six segments (12 tracks). Adjacent tracks have inverse azimuths. On each track of an even segment, an auxiliary data sync block is recorded at the position of a trailing end of a video sector v1. On each track of an odd segment, an auxiliary data sync block is recorded at the position of a leading end of the video sector v1. Since the auxiliary data sync blocks are recorded at distant positions on the tape, failure to read the auxiliary data at all due to a flaw in the longitudinal direction of the tape may be prevented.
