Abstract:
A thin film magnetic head comprising:a main magnetic pole piece;a magnetoresistance effect element;a bias layer giving a bias magnetic field to said magnetoresistance effect element;an auxiliary magnetic pole piece;an insulating layer leaving a space between said main magnetic pole piece and said auxiliary magnetic pole piece; andwherein said main magnetic pole piece is almost disposed partly in the same plane with said magnetoresistance effect element; a distance between said main magnetic pole piece and said magnetoresistance effect element is selected from 1 nm to 1 .mu.m and further wherein the main magnetic pole piece is a continuous member with a portion that is substantially parallel to a top surface of the magnetoresistance element that is formed over the entire magnetoresistance effect element and wherein end portions of the main magnetic pole piece are partly disposed in the same plane of the magnetoresistance element.
