。 In an intermittent drive circuit that drives a tape intermittently, a sampling pulse creation means that creates a sampling pulse based on an RF switching pulse, a hold means that holds a reproduction envelope at the timing of the sampling pulse, and a braking pulse width and/or slow changing means for changing the amount of tracking delay in relation to tape stopping;
It is characterized by comprising a direction determining means for determining the direction of change in the output of the holding means based on a change in the braking pulse width and/or slow tracking delay amount and controlling the changing means in a direction in which the reproduction output envelope becomes larger. Intermittent drive circuit.
