Apparatus and method for respectively recording digital video and audio signals in both ends portions and middle portion of each inclined track of magnetic tape

摘要

In an apparatus and method for recording inputted digital video and audio signals of one field, which are synchronous with each other, onto a plurality of inclined tracks of a magnetic tape using a plurality sets of helical scan type magnetic heads provided in a rotation head drum at predetermined angle intervals, a read clock is generated. A read address of a first field memory is generated based on the read clock, so that the inputted digital video signal is read out and recorded onto both end portions of each of the inclined tracks of the magnetic tape, after starting recording the inputted digital video signal of one field onto an end of the inclined track, and ending recording the inputted digital video signal of one field onto another end of the other inclined track. On the other hand, a read address of a second field memory is generated based on the read clock, so that the inputted digital audio signal is read out and recorded onto the middle portion of each of the inclined tracks.
