PURPOSE:To obtain the reproduction output of digital magnetic recording with a simple circuit by using an RS flip-flop. CONSTITUTION:A reading magnetic head 1 is connected to an RS flip-flop 10 by way of an operational amplifier 2, transformer 5, diodes 6, 7 and waveform amplifiers 8, 9. As a result, the leading edge differentiation signal and trailing edge differentiation signal of the magnetic recording signal having been read with the reading magnetic head 1 are respectively amplified, rectified and shaped, after which they are inputted to the RS flip-flop 10, then the leading edge differentiation signal sets or resets the RS flip-flop 10 and the trailing edge differentiation signal resets or sets the same, thus the output of the RS flip-flop 10 becomes reproduction signal. Hence, the reproduction signal may be obtained without using any differentiation circuit and integrating circuit. |
