Thin film magnetic head with improved insulating properties and method of manufacturing the same

摘要

The thin film magnetic head has insulating layers and a MR element section, which has uniform thickness and which can be formed on a surface of a magnetizable substrate with enough insulating strength. In the thin film magnetic head, a magnetizable metal layer is formed on a surface of the magnetizable substrate. A first insulating layer is formed on a surface of the magnetizable metal layer. The MR element section for reproducing data is formed on a surface of the first insulating layer. A second insulating layer is formed on the MR element section so as to sandwich the MR element section between the first insulating layer and the second insulating layer. A shielding layer is formed on a surface of the second insulating layer.
