CONSTITUTION:A front yoke 13 and a back yoke 14 are formed on a substrate 11 by bulk material like an Ni-Zn-ferrite and are cut into thin films. A thin film MR element 16 is arranged between yokes 13 and 14 so that it is electrically insulated but magnetically coupled. Since yokes 13 and 14 are formed with bulk material, the surface state is satisfactory and a magnetic barrier is difficult to occur, and the Barkhausen noise is prevented. Since the front yoke 13 is completely a thin film, it is prevented from peeling and wearing due to run of a magnetic tape 21.,下面是Yoke type thin film magnetic head专利的具体信息内容。
