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 having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer on the medium-opposing surface side, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated on a substrate. This thin-film coil has a plurality of turn parts arranged at respective positions having different distances from the medium-opposing surface, while a non-expandable part made of an insulating material having a coefficient of thermal expansion smaller than that of a photosensitive resin is formed between the turn parts.
