Abstract:
A method of making a magnetic head that has an air bearing surface (ABS), comprising:forming a read head;forming a ferromagnetic first shield layer;forming a nonmagnetic electrically insulative first gap layer on the first shield layer;forming a read sensor and first and second lead layers connected to the read sensor on the first gap layer;forming a nonmagnetic electrically insulative second gap layer on the read sensor, the first and second lead layers and the first gap layer;forming a ferromagnetic second shield layer on the second gap layer;at least one of the shield layers comprises a laminated film which includes at least one Fe--Al--N--O layer and at least one nonmagnetic layer; andsaid at least one Fe--Al--N--O layer being formed by sputtering with N.sub.2 O as a reactive gas.
