Title: Detecting circuit for resistance change
Inventor: SATOU NAOKI
IPC: G11B5/02
Filed: 1983-08-15
Abstract: PURPOSE:To improve the resistance to external noise with a detecting circuit for resistance change of an element having its own resistance varying with external factors, by using a pair of base-earthed transistors. CONSTITUTION:The emitters of a pair of base-earthed transistors TRs 13 and 14 having different base potentials are connected to both ends of a magneto-resistance effect magnetic head 1. Thus the potentials are kept constant at both ends of the head 1. This keeps the initial value of current density despite the change of resistance value of the head 1. The change of resistance value of the head 1 is turned into changes with phases opposite to each other for collector currents of the TRs 13 and 14. In this case, the current is supplied from a current source 2 having a high impedance. As a result, the impedances have an equal level between both ends of the head 1 and the differential amplification is attained. Therefore the external noise of the same phase can be eliminated. In this way, the resistance to external noises is improved.
