Thin film magnetic head that has solenoid type recording coil
摘要:
A thin film magnetic head is provided. The thin film magnetic head includes an upper coil wire group and a lower coil wire group. Two columns of coil contact groups that are formed on both end portions of individual coil wires of the upper coil wire group and the lower coil wire group, connect both end portions of the coil wires. An insulating resist layer buries a space between coil contacts of the coil contact groups. An inorganic insulating layer buries a space between the two columns of coil contact groups. The upper coil wire group, the lower coil wire group, and the two columns of coil contact groups form a thin film coil that applies a magnetic recording field to the magnetic material layer. The insulating resist layer and the inorganic insulating layer are located at the same lamination height as the two columns of coil contact groups.
