レコーダ。[Claims for Utility Model Registration] A first rotating head group consisting of two adjacent heads with different azimuth angles, and a second rotating head group consisting of two adjacent heads with different azimuth angles. In a double azimuth four-head video tape recorder, the first and second heads correspond to the heads having different azimuth angles and demodulate the reproduced signals from the heads.
a demodulator; a phase reference signal generation circuit that generates a phase reference signal by removing time fluctuations in a horizontal synchronization signal from among the reproduction signals from the head; and a phase reference signal generation circuit for generating a phase reference signal from among the reproduction signals from the first and second demodulators first and second PLs that output a delay control signal for phase-locking the horizontal synchronization signal of the phase reference signal to the phase reference signal;
an L circuit, and first and second circuits that respectively delay the reproduced signal based on delay control signals from each of the PLL circuits.
A video tape recorder comprising a delay circuit.
