Abstract: PROBLEM TO BE SOLVED: To equalize a signal from a vertical recording medium reproduced through an MR head with the reproduced signal from a longitudinal recording medium by an arrangement wherein an inflection point frequency exists in each frequency band obtained by dividing a desired frequency band by the number of steps of a plurality of differentiating circuit connected in cascade. SOLUTION: The band 0.2-32.5 MHz of a reproduction signal required for transmitting 90% of the energy of a 65 Mbps digital signal is denoted by band (W90).

Each circuit 1-3 is allocated with an inflection point frequency f1-f3 and a specific band coefficient m1-m3 such that an inflection point frequency and a phase change band are included in each divided frequency band thus determining circuit constants. When the specific band coefficients m1-m3 are distributed substantially equally to respective stages, the combined phase characteristics has a phase lead of 90 deg. when the inflection point frequencies f1-f3=0.47, 2.6, 1.40 MHz and the specific band coefficients m1-m3=6.0, 6.6, 5.5.
