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, and a thin-film coil are laminated on a substrate. The thin-film magnetic head has a shield magnetic layer. The shield magnetic layer has a leading shield part. The leading shield part is disposed on a substrate side of the main magnetic pole layer. The leading shield part has a variable distance structure in which a rearmost part most distanced from the medium-opposing surface is distanced more from the main magnetic pole layer than is a foremost part on the main magnetic pole layer side. |
