Abstract
PURPOSE: To make it possible to regenerate a video signal, whose phase characteristics are canceled, with fidelity by providing a reverse resonance circuit and amplitude limiting circuit to a write system and a resonance circuit to a read system.
CONSTITUTION: A FM-modulated signal from input terminal 103 is recorded on tape 11 by head 12 by way of reverse resonance circuit 4 with a reverse resonance point near its carrier frequency, amplitude limiting circuit 5 and amplifier 6 with flat frequency characteristics. Then, the output of head 13 is regenerated through resonance circuit 7 with a resonance point nearly equal to the reverse resonance frequency and FM equivalent circuit 8. In this way, waveform distortion can be eliminated by canceling phase characteristics between a write-side circuit and read- side circuit, and the conventional dynamic range of a write amplifier can be secured by providing the amplitude limiting circuit to the write-side circuit.
