PURPOSE:To momentarily synchronize a reproduced signal and the reference clock signal from a PLL circuit with each other at the time of switching from the recording or erase mode to the reproducing mode. CONSTITUTION:In accordance with input of a reproducing start command signal, a closing circuit 6 connected to a capacitor C of a loop filter 3 closes the contact to discharge the potential held in the capacitor C of the loop filter 3. Thus, such control voltage is outputted to a voltage control circuit 4 that the output signal of the voltage control circuit 4 is immediately synchronized with the reproduced signal. |
