    • PROBLEM TO BE SOLVED: To accurately form a magnetic pole layer of a desired shape in a magnetic head for perpendicular magnetic recording, and a method of manufacturing the same. SOLUTION: The magnetic head is provided with an accommodation layer 15 made of a non-magnetic material and having a groove 15a that opens in the top surface, a non-magnetic metal layer 17 made of a non-magnetic metal material having a penetrating opening that is continuous to the groove 15a, and arranged on the top surface of the encasing layer 15, and a pole layer 24 made of a magnetic metal material and accommodated in the groove 15a of the accommodation layer 15 and in the opening 17a of the non-magnetic metal layer 17. The end face of the pole layer 24 arranged at a medium facing surface has a first portion 41 and a second portion that is loacated apart from a substrate at the first portion and connected to the first portion. The width of the first portion 41 is decreased as a distance from the substrate is decreased. The second portion 42 has a uniform width that defines the track width. On the medium facing surface, the non-magnetic metal layers 17 exist on both sides of the second portion 42 in the direction of the track width. COPYRIGHT: (C)2006,JPO&NCIPI
