Thin-film magnetic head

Abstract

Abstract PURPOSE:To increase the electromagnetic conversion factor, by forming a coil even at the triangle part which cannot be eliminated by the etching of the laminated resin layer. CONSTITUTION:The 2nd layer smaller than the 1st layer is formed on the coil pattern 110 of the 1st layer. And the 2nd layer has 3 turns when the 1st layer has 4 turns. In this instant, the center terminal is led out of the 6th-turn coil which is positioned at the middle point, and at the same time the 1-turn 114W which is nearest to the head cap among the coil patterns of the 2nd layer is connected to the half-coil part of the rest 5 turns which is formed with the coil pattern 118 of the 3rd layer and the coil pattern 122 of the 4th layer. As a result, the coil can be formed at the triangular part nearest the head cap of the trapezoid multilayer coil part which is formed when the etching is applied finally to the laminated layer resin.
