摘要： PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording head capable of achieving high recording performance and stability, and its manufacturing method.
SOLUTION: On the trailing side of a main magnetic pole layer 15, a gap layer 17 extending backward from an air bearing surface 40, and an auxiliary magnetic pole layer 19 extending backward from a position retreated more than the air bearing surface 40 are arranged, and the auxiliary magnetic pole layer 19 partially overlaps the gap layer 17. When the auxiliary magnetic pole layer 19 is formed by using an etching method in the manufacturing process of the perpendicular magnetic recording head, the gap layer 17 functions as an etching stopper layer to protect the main magnetic pole layer 15. Thus, an etching process does not reach the already formed main magnetic pole layer 15. Since the thickness of the main magnetic pole 15 is maintained as a design value during formation of the auxiliary magnetic pole layer 19, magnetic flux saturation is difficult to occur in the main magnetic pole layer 15.
