Abstract
A magnetic tape recording/reproducing device samples analog acoustic signals and converts the signals into digital acoustic signals. Analog video signals are sampled for every field and converted into digital video signals. The converted digital acoustic signals and digital video signals are recorded sequentially on a magnetic tape so that both the digital acoustic and digital video signals can be reproduced properly.
