Thin-film magnetic head having slider body formed of ferrite |
摘要 |
A thin-film magnetic head including: a slider body formed of a ferrite material and having air bearing portions on one major surface thereof on which a magnetic recording medium is slidable; a non-magnetic layer formed in the slider body such that the non-magnetic layer is located at least on a trailing end face of each of the air bearing portions, the non-magnetic layer having a thickness of at least 20 (my)m; a head portion including an upper and a lower magnetic layer and a coil which are positioned within an area of the non-magnetic layer. The lower magnetic layer, the coil and the upper magnetic layer are laminated on the non-magnetic layer such that the upper and lower magnetic layers constitute a closed magnetic path, and such that a magnetic gap is formed between the upper and lower magnetic layers and is open in a top face of each air bearing portion.
