ABSTRACT:
In a thin film magnetic head including a substrate, a lower shield layer formed on the substrate, a first non-magnetic layer formed on the lower shield layer, a common magnetic pole formed on the first non-magnetic layer to be operable as both an upper shield layer and a lower magnetic pole, a second non-magnetic layer formed on the common magnetic pole, a conductive coil which is formed on the second non-magnetic layer through a first-insulation layer and which is overlaid by a second insulation layer, and an upper magnetic pole formed on the second insulation layer, a front end of the upper magnetic pole is directly kept in contact with the first non-magnetic layer while a rear end of the upper magnetic pole is directly kept in contact with the common magnetic pole. An element of magnetoresistance effect is provided in a front end of the first non-magnetic layer. An area (e.g., width); and of the common magnetic pole is not larger than an area (e.g., width) of the upper magnetic pole.
