Thin film magnetic heads and a method of producing the same |
摘要 |
A thin film magnetic head has a magnetic gap and two magnetic films that hold the magnetic gap therebetween to form a magnetic circuit. At least one of the two magnetic films has a first portion the surface of which is located remote from a throat height=0 point, and exposed to a recording medium and which determines a recording track width, and a second portion not exposed to the recording medium. The cross-sectional area of magnetic path in the second portion is larger than that in the first portion.
