Abstract

PURPOSE:To prevent earth return phenomena and to reduce the abrasion of a recording stylus by so arranging the method that the average value of the part of positive AC voltage for performing electrorecording is made smaller than the absolute value of the average part of a negative part. CONSTITUTION:A diode D1 and a diode D2 which are connected in series to a resistance R are inserted in parallel between an AC power source 6 and a recording stylus 4. Hence, the current i2 of a positive half wave flowing form the power source 6 to the stylus 4 decreases as compared to the current i1 of a negative half wave.
