Thin-film magnetic head, method of manufacturing the same, head gimbal assembly, and hard disk drive |
摘要 |
A thin-film magnetic head is constructed such that a main magnetic pole layer, a write shield layer, a gap layer, a thin-film coil and a shield magnetic layer are laminated on a substrate. The thin-film magnetic head has a shield magnetic layer. This thin-film magnetic head has a hard guard frame layer surrounding an equidistant coil part, disposed at a position equidistant from the substrate, from outside and being in direct contact with almost a whole outside surface defining an outer shape of the equidistant coil part. |
