Abstract

PURPOSE:To produce a double integral waveform of staircase waves with a simple circuit constitution, by outputting the pulse obtained through time division and multiplex of positive and negative pulses as a control pulse for a reproducing converter feeding. CONSTITUTION:To compulsively carry a reproducing converter which picks up and reproduces the already recorded information signal of a rotating recording medium toward the radial direction of the rotating recording medium, a double integral waveform in staircase wave is outputted as a control pulse. In this case, positive pulse according to the carrying period of a reproducing converter is outputted to an output terminal of a feed timing logical circuit 20, and a high or low level signal is outputted to an output terminal B according to the direction of carrying of the reproducing converter. Thus, desired control pulses for reproducing converter feed can be produced at a terminal 34.
