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.
