摘要： A method for manufacturing a thin film magnetic head with a write element, the write element having a first yoke portion and a second yoke portion connected to each other by a back gap portion, a first pole portion and a second pole portion disposed in the medium-facing surface side of the first yoke portion and the second yoke portion respectively, a gap film disposed between the first pole portion and the second pole portion, and a coil surrounding in a spiral form the back gap portion, and the manufacturing method including the steps of forming the coil above the first yoke portion, forming a part which the first pole portion is composed of so that the part extends to cover the upper surface of the coil, forming the gap film on the first pole portion, forming the second yoke portion, which includes the second pole portion, above the gap film, and trimming the first pole portion so as to have a width fitting the second pole portion.

摘要： A thin-film magnetic head is manufactured as follows. First, a base insulating layer having a magnetic pole forming depression sunken into a form corresponding to the main magnetic pole layer is formed, a stop film for CMP is formed such as to fill the magnetic pole forming depression, and then a magnetic layer is formed on the stop film. Next, the magnetic layer is separated by forming a separation groove substantially surrounding the magnetic pole forming depression on the outside thereof, and thus separated magnetic layer is formed with a cover insulating film adapted to cover the whole upper face. The surface is polished by CMP until the stop film is exposed, so that the part of magnetic layer remaining on the inside of the magnetic pole forming depression is used as the main magnetic pole layer. Further, a recording gap layer, a write shield layer, and a thin-film coil are formed.
