Abstract

PURPOSE: To ensure the reading detection in a high efficiency and good balance and at the same time to avoid the effect of the crosstalk, by forming the bridge circuit with the dummy element circuit constituting the detector plus the serial-connection magnetic resistance element itself of the detecting element circuit.
CONSTITUTION: The parallel connection is secured between power source E and the earth for the detecting element circuit and the dummy element circuit formed by two even units of serial magnetic resistance elements 21/22 and 23/24 each. And then the both central contacts of elements 21/22 and 23/24 are connected to detecting amplifier 100. In such way, the bridge circuit of the reading detector can be constituted with elements 21W24 themselves and without using any external resistance or the like. Accordinly, no consideration has to be given to the deviation of the external resistance, and thus the reading detection is always possible for the magnetic bubble in the maximum efficiency. Furthermore, the opposite polarity is secured for the crosstalk in elements 23 and 24 each caused by magnetic bubbles BO and BE to which transfer patterns 31 and 32 are given. Thus a high S/N is secured with no effect of crosstalk for the composite detection value obtained through amplifier 100.
