Perpendicular magnetic head and method for manufacturing the same |
摘要 |
A perpendicular magnetic recording head includes a primary magnetic pole having a flat top surface. The magnetic head also includes a shield layer over the primary magnetic pole and at the sides of the primary magnetic pole in a single piece. The distance in the direction perpendicular to the thickness direction between the side surfaces of the primary magnetic pole and the side shield layer is longer than the distance in the thickness direction between the top surface of the primary magnetic pole and the shield layer.
