Abstract

PURPOSE: To obtain an output waveform that is stable against fluctuations of revolving magnetic field intensity, those of ambient temperature, those of chip manufacture process, etc., by forming a magnetic bubble detector of a soft ferromagnetic multilayered thin film differing in film quality.
CONSTITUTION: The magnetic bubble detector is made of soft ferromagnetic thin film 4 of double-layer lamination structure obtained by stacking two kinds of thin film 2 and 3 made of soft magnetic-substance differing in film quality. Output waveform W2 of "1" from this detector is that with a specific peak and increases extremely and its output voltage becomes high. Therefore, decisions on "1" and "0" can securely be made by setting the strobe point in the center of the peak.
