PURPOSE:To disperse a heat source so as to suppress temperature rise of an MR head, by uniting plural resistors for constant current and plural capacitors for introducing signals in one body independently from plural magneto-resistance effective elements. CONSTITUTION:A capacitor array 27' is increased by two in the number of its capacitor elements incorporated therein from conventional examples and the two capacitors are used as capacitors Cb and Cbb for stabilizing a power source S for constant current and another power source B for IC, respectively. In this case, the wiring pattern of a printed circuit board 30' is changed in a desired way, such as a terminal for IC power source is installed, etc. A resistor block 40 is formed in such a way that a desired number of resistance elements for constant current are installed to one surface of a ceramic substrate 41 and a power supply terminal 42 and constant current supplying terminal 43 are installed to the IC side and head side of the substrate 41. Therefore, no resistance element for constant current is installed to the magnetic substrate 1' of an MR head H'. |
