ABSTRACT:
A thin-film magnetic head having a slider and electromagnetic transducers provided at an end portion on one side of the slider. The magnetic head comprises a plurality of wire connecting portions connected with the electromagnetic transducers and arranged in a row on the surface of the slider which is opposite to that surface of the slider facing a magnetic recording medium. Such a thin-film magnetic head is manufactured by preparing a pair of thin-film magnetic head preforms which each have a plurality of wire connecting portions, and which are positioned in symmetrical relation to each other with their respective wire connecting portions disposed in mutual back-to-back abutment, the mutually abutting wire connecting portions each consisting of an electrode. The preforms are then bisected so as to obtain two thin-film magnetic heads.
