ABSTRACT:
Provided is a method of manufacturing a thin film magnetic head capable of manufacturing a thin film magnetic head with as high performance as possible. A magnetic pole layer is formed so as to have a laminate structure in which an auxiliary magnetic pole layer (including an adjacent portion and a nonadjacent portion) extending from a first flare point to the rear and a main magnetic pole layer (including a front end portion and a rear end portion) extending from an air bearing surface to the rear through the first flare point are laminated in this order. As (1) a recording track width is controlled with high precision through forming the main magnetic pole layer with high precision, (2) recording is stably performed by an increase in the amount of magnetic flux contained in the main magnetic pole layer, and (3) information recorded on a recording medium is stably maintained through preventing information erasing without intention, the thin film magnetic head can achieve higher performance.
