ABSTRACT:
In a detector of an magnetic bubble memory device of the type comprising a magnetic bubble memory element having a detector, a source of constant current for passing constant current through the detector for producing a bubble output signal according to the magnetoresistive effect of a detector, a preamplifier for amplifying the output signal, a DC regenerator for regenerating an output signal of the preamplifier and a discriminator for converting the DC regenerated signal into a binary code, there is provided a holding circuit connected between the DC regenerator and the discriminator for holding a peak value of the DC regenerated signal for a predetermined time.
