Thin film magnetic head having a bottom pole layer, a gap layer, and a top pole layer which are formed by plating |
摘要 |
The present invention provides a thin film magnetic head in which a first coil layer is formed at the back of a track width control portion. The first coil layer being located nearer a bottom core layer than the junction surface of a track width control portion and an upper core layer. With a two-layer structure, the width of the coil layer can be decreased. The height from the top of the bottom core layer to the top of an insulating layer can be decreased. The insulating layer covering a second coil layer can be decreased, thereby shortening the magnetic path and decreasing inductance.
