Abstract

PURPOSE:To perform DC reproduction at an excellent S/N ratio by detecting a peak value by clamping the detection output of a magnetic bubble memory at the input terminal of a differential amplifier which converts said detection output into a logic signal. CONSTITUTION:When a magnetic bubble is positioned at the detector 6 of a magnetic bubble memory element 5, the resistance of the detector 6 increases and its detection signal which corresponds to said increase is detected through a preamplifier 14 and applied to a differential amplifier 20 provided with a clamping diode 17 at its intput side. If transistors (TR) 21 and 22 are turned off before the detection output 2 has a positive peak value 2a, an input to the positive terminal of the amplifier 20 is clamped by a diode 17 to the potential of the peak value 2a, and DC reproduction is performed with the positive peak value to output a high-level logic signal from the amplifier 20. The output detecting circuit of the magnetic bubble memory which performs the DC reproduction at an excellent S/N ratio is obtained by a system which detects the peak value.
