ABSTRACT:
In a high definition television system (HDTV), a video signal is recorded on and reproduced from oblique and successive parallel tracks on a magnetic tape, and an audio signal is recorded on and reproduced from a plurality of parallel tracks extending in a longitudinal direction of the tape. The tape is transported in its longitudinal direction during recording and reproduction. A tape position adjuster adjusts the position of the magnetic tape in its transport direction, and first and second transducing heads located at positions separated by a predetermined distance which may vary slightly because of manufacturing tolerances are employed for respectively reproducing and recording the audio signal. When the tape is edited, a processor connected to the first transducing head processes a reproduced audio signal and supplies it to the second transducing head, which records it accordingly. A controller responsive to an output signal of the adjuster controls the processor so as to shift the recording timing of the second transducing head as may be necessary to prevent the accumulation of recording timing errors during successive edits of the tape.
