Abstract
A thin film magnetic head of the present invention is configured to include a main pole layer; a main pole direct junction magnetic layer that has an auxiliary pole layer and an auxiliary yoke layer, the main pole direct junction magnetic layer being directly joined to the main pole layer in a state where a recording gap layer is partially intervened near an air bearing surface (ABS) with respect to the main pole layer; and a first magnetic recording exciting coil that is buried between the auxiliary pole layer and the auxiliary yoke layer configuring the main magnetic direct junction magnetic layer with an insulating layer therebetween. Thereby, an effective magnetic path length can be shortened in order to improve the high-frequency characteristics, and furthermore, simplification of the manufacturing processes becomes possible.
