回路。 In a reproducing circuit that reproduces the output from a magnetic head via a filter section and a differentiator, the gain of this reproducing circuit is kept low in the high range of the frequency band used, and the delay characteristics fluctuate in this band. A reproducing circuit characterized in that constants of the filter section and the differentiator are respectively set so that fluctuations in the delay characteristics of the filter section and fluctuations in the delay characteristics of the differentiator cancel each other out in order to reduce the width.
