Abstract

PURPOSE:To avoid unsymmetrical wear at end surface machining for magnetic heads, by providing a plurality of sets of conductor groups at the specific position up and down the magnetic substance of the multi-channel type thin film magnetic head, and monitoring the state of wear through the detection of the progress of open wire of the conductor wires. CONSTITUTION:On the transparent substrate 6, the thin film magnetic resistor type head(MR head) 2 and the conductor layer 3 are provided. The lower conductor pattern 7 arranged in parallel with the polished surface under the substrate 6 and provided for a plurality vertically is formed and the protective cover 9 is covered via the adhesives 8. The horizontal conductor pattern 11 is provided in parallel with the polished surface with a plurality on the transparent insulation layer 10 on MR element 2 and layer 3, and the transparent spacer 13 is provided via the adhesives 12 with the pattern 11. The conductor pattern 14 is formed on it with the pattern 7 and it is covered with the protective cover 16 via the adhesives 15. Next, the polishing tape 5 exposes the end surface of the MR element 2 to constitute the head surface. The unsymmetrical wear can be avoided by detecting the open wire of the conductor pattern 7, 11, 14 accompanied with the progress of polishment.
