Abstract
A digital video tape recorder comprises a rotary transducer head arrangement comprising an advance read head and a confidence head both capable of reading audio signals recorded in portions of oblique tracks on a magnetic tape, the heads being positioned relative to one another such that an audio signal at any given position on the magnetic tape reaches the advance read head a predetermined time before the same signal reaches the confidence head, and a delay device for delaying the output of the advance read head by that predetermined time.
