发明名称 Thin film yoke-type magnetoresistive head
摘要 A thin film magnetic head including a lower yoke made of magnetic material having a high permeability, a magnetoresistive element and an upper yoke for transmitting magnetic flux to the magnetoresistive element. The upper yoke overlaps, at its rear end portion, a front end portion of the magnetoresistive element, while the lower yoke is formed, at its portion confronting the magnetoresistive element, with a groove such that the magnetoresistive element overlaps, at its rear end portion, the lower yoke.
