Abstract

PURPOSE: To record and reproduce audio signals with high quality by providing rotary head pairs and simultaneously recording and reproducing the video signal and PCM audio signal of a VTR.
CONSTITUTION: Four rotary heads 4a thru 4c are provided at a division of 90° to the rotary drum 1 of a VTR 10 and a magnetic tape moves while being coiled on the drum 1 over 180°. Head pairs 4a and 4c, 4b and 4d are formed by these heads 4a thru 4c. The video signal is processed simultaneously by the heads 4a, 4b and the PCM audio signal by the heads 4c, 4d. As compared to the case of processing the audio signal by using a stationary head to the tape end part, the audio signal may be processed in synchronization to the video signal with high quality.
