Abstract

PURPOSE:To make a VTR of surface and deep layer recording perform optimum control, by controlling tracking by adding digital signals in which the reproducing signals of a rotary video head and a rotary HIFI audio head are envelope- detected and converted, respectively. CONSTITUTION:A signal reproduced by the rotary video heads 4a and 4b is detected at a video signal envelope detection circuit 43, and after being converted to the digital signal at an A/D conversion circuit 45, is stored in a memory circuit 47. Also, the signal reproduced by the rotary HIFI audio head 40a and 40b is detected at an HIFI audio signal envelope detection circuit 44, and after being converted to the digital signal at an A/D conversion circuit 46, is stored in a memory circuit 48. The voltage values of the circuits 47 and 48 are impressed on a microcomputer 49, then, added. A tracking control signal generation circuit in the microcomputer 49 generates a tracking control signal which represents an amount of tracking in which an added synthesis envelope value becomes the maximum, and the speed of a capstan motor 9 and the amount of tracking are controlled based on the signal.
