Patent ID: 7061718

Claim:
A thin film magnetic head comprising: a substrate having a major surface; a first magnetic layer formed on or above the major surface of the substrate and having a pole portion; a second magnetic layer having a pole portion which is opposed to said pole portion of the first magnetic layer via a write gap layer and constitutes an air bearing surface together with said pole portion of the first magnetic layer, and a rear portion; a third magnetic layer having a front portion connected to the rear portion of said second magnetic layer, a front end surface of said front portion being positioned near the air bearing surface but displaced rearwardly in a direction of the rear portion of the second magnetic layer, and a rear portion of the third magnetic layer being magnetically coupled with the first magnetic layer at a position remote from the air bearing surface; and first and second layers of thin film coil having portions formed between said first and second magnetic layers; wherein said first layer of thin film coil is embedded within a first insulating layer; a second insulating layer is provided on the first insulating layer such that a surface of the second insulating layer opposite to the first insulating layer is coplanar with a surface of the rear portion of the second magnetic layer opposite to the write gap layer; and the second layer of thin film coil is formed on the coplanar surface of the second insulating layer and is embedded within a third insulating layer.
