Abstract

PURPOSE:To easily form the gap dipth with high accuracy, by forming a resistor with the same material as the magnetic layer of an element, connecting it to a parallel circuit and allowing the change of a resistance value to be a step-shape. CONSTITUTION:The same material as a lower core and an upper core is used for the resistor and the parallel circuit is formed by utilizing the upper and lower cores. Then, a resistance change is allowed to be changed in the step- shape. Further, the resistor is formed with the same process as an element 3 and the point of the gap dipth (MGD) '0' of a monitoring pattern 2 is formed in the same position as the MGD '0' of the element 3 so that the MGD can be easily controlled. Thus, the gap dipth with the high accuracy can be easily formed.
