Abstract
PURPOSE: To eliminate uneven revolution by eliminating frequency fluctuation caused by amplitude modification by making flctuation in input wave form pro produced by uneven machining, eccentricity and the like of a gear plate coupled with a revolving axis driving the revolving magnetic head go through a half-wave rectifier circuit and a differential circuit with setting a phase in operation level of an amplifier at constant.
