发明名称 Perpendicular magnetization type magnetic head having a magnetic pole part which forms a closed magnetic path
摘要 A perpendicular magnetization type magnetic head comprises a main magnetic pole part wound with a coil, for subjecting a magnetic recording medium to magnetic fluxes which pass perpendicularly through a magnetic layer of the magnetic recording medium, a non-magnetic part located on both sides of the main magnetic pole and adjacent to the magnetic recording medium, so as to sandwich the main magnetic pole, and a closed magnetic path forming magnetic pole part for forming a closed magnetic path of the magnetic flux with respect to the main magnetic pole part. The closed magnetic path forming magnetic pole part has an edge which is bounded on the non-magnetic part. This edge is non-parallel to the main magnetic pole part.
