Abstract
A magnetization characteristic measurement device includes a differential magnetic head, a signal generator for exciting the differential magnetic head with a low frequency signal, a magnetic head moving device for moving the differential magnetic head to a predetermined measuring position, a measured data converting device for sampling the differential output voltages from the magnetic head when it is positioned at the predetermined position and for converting the sampled values into digital values, and a measured data analyzing device for sequentially storing the obtained digital values and for calculating the magnetizing characteristics. The structure allows for simple and easy measurement of magnetization characteristics of magnetic thin films attached to a magnetic printing, magnetic tape, etc. by simply setting the magnetic thin film at a position. The result of the measurement is displayed on a display screen or indicated using a buzzing sound to thereby reduce inspection steps. Since the quality is displayed in reference to a predetermined standard, standardization of quality can be easily achieved.
