摘要：
A thin film magnetic head employs antiferromagnetic and ferromagnetic layers in a layered structure to provide magnetic exchange field coupling. This structure is provided with a buffer layer which is in contact with either the ferromagnetic layer or the antiferromagnetic layer and whose action enhances the exchange field coupling between the antiferromagnetic and ferromagnetic layers and improves the corrosion resistance.
