A signal characteristic variation apparatus for a high definition VCR in which a characteristic of a video signal transmitted is varied according to characteristics of a tape and a channel. A predetermined frequency band of test signal is recorded and played back on/from the tape for discrimination of the tape and channel characteristics in a recording mode. Therefore, the video signal can stably be recorded on the tape with its characteristic adjusted according to the discriminated tape and channel characteristics. In a playback mode, the tape and channel characteristics are discriminated by detecting the test signal recorded on the tape.
